The Gibbs free energy equation we will be working with is Delta or change in G is equal to change in enthalpy minus temperature multiplied by. What is the value of delta G for the precipitation of AL(OH)3 at 25 C? This is what I came I then solved for x^2 and plugged it into the equation. By maximum delta-v, I meant for an all-purpose vehicle, but thanks for the . I think there's a difference in philosophy and gameplay style here.

And so, we get So, now we have So, how do we solve for K here? Well, we would take E to both sides. So, if we take E to the So, let's take E to the And since we're dealing with gases, if you wanted to put in a KP here, you could. So, now we have an equilibrium constant, K, which is much greater than one. And we got this value from a negative value for delta-G zero. So, let's go back up to here, and we see that delta-G zero, right, is negative. So, when delta-G zero is less than zero, so when delta-G zero is negative, what do we get for our equilibrium constant?

We get that our equilibrium constant, K, is much greater than one. So, what does this tell us about our equilibrium mixture? This tells us that at equilibrium, the products are favored over the reactants, so the equilibrium mixture contains more products than reactants.

And we figured that out by using our value for delta-G zero. Let's do the same problem again, but let's say our reaction is at a different temperature. So now, our reaction is at Kelvin, so we're still trying to make ammonia here, and our goals is to find the equilibrium constant at this temperature. At Kelvin, the standard change in free energy, delta-G zero, is equal to zero.

So, we write down our equation, delta-G zero is equal to negative RT, a natural log of the equilibrium constant, K. And this time, for delta-G zero, we're plugging in zero. So, zero is equal to, we know that R is the gas constant, and we know that the temperature here would be Kelvin.

So, for everything on the right to be equal to zero, the natural log of K must be equal to zero. So, we have zero is equal to the natural log of K. And now, we're solving for K, we're finding the equilibrium constant. So, we take E to both sides. So, E to the zero is equal to E to the natural log of K.

E to the natural log of K is just equal to K. So, K is equal to E to the zero, and E to the zero is equal to one. So, when delta-G zero is equal to zero, so let's write this down on here, so, when your standard change in free energy, delta-G zero, is equal to zero, K is equal to one.

And that means that at equilibrium, your products and your reactants are equally favored. Let's do one more example. So, let's find the equilibrium constant again at another temperature. So, now we're at K, and our standard change in free energy, delta-G zero, is equal to positive So, delta-G zero is equal to negative RT, natural log of K.

This time, we're putting in positive So, let's do the math there. We'll start with our delta-G zero, which is So, we're going to take that value and divide it by negative 8. So, we have negative So, to solve for the equilibrium constant, we take E to both sides, and we get that K is equal to E to the negative So, what is that equal to? As temperature increases, kinetic energy increases.

The greater kinetic energy results in greater molecular motion of the gas particles. As a result, the gas particles dissolved in the liquid are more likely to escape to the gas phase and the existing gas particles are less likely to be dissolved. The converse is true as well. The trend is thus as follows: First, note that the process of dissolving gas in liquid is usually exothermic.

As such, increasing temperatures result in stress on the product side because heat is on the product side. Consequently, the equilibrium concentration of the gas particles in gaseous phase increases, resulting in lowered solubility.

Conversely, decreasing temperatures result in stress on the reactant side because heat is on the product side. Consequently, the equilibrium concentration of the gas particles in gaseous phase would decrease, resulting in greater solubility. Pressure Affects Solubility of Gases The effects of pressure are only significant in affecting the solubility of gases in liquids. The effects of pressure changes on the solubility of solids and liquids are negligible.

Consider the following formula of Henry's law: This formula indicates that at a constant temperature when the partial pressure decreases, the concentration of gas in the liquid decreases as well, and consequently the solubility also decreases.

Conversely, when the partial pressure increases in such a situation, the concentration of gas in the liquid will increase as well; the solubility also increases. Consider a system consisting of a gas that is partially dissolved in liquid. An increase in pressure would result in greater partial pressure because the gas is being further compressed. This increased partial pressure means that more gas particles will enter the liquid there is therefore less gas above the liquid, so the partial pressure decreases in order to alleviate the stress created by the increase in pressure, resulting in greater solubility.

The converse case in such a system is also true, as a decrease in pressure equates to more gas particles escaping the liquid to compensate. Pressure and temperature are increased? Pressure is increased but temperature is decreased? The change in solubility cannot be determined from the given information.

Increasing pressure increased solubility, but increasing temperature decreases solubility An increase in pressure and an increase in temperature in this reaction results in greater solubility. An increase in pressure results in more gas particles entering the liquid in order to decrease the partial pressure. Therefore, the solubility would increase.
