Determining Which side is favored

Postby Victoria Luu - 1C » Sun Jan 13, 2019 8:36 pm

Why is it that when Q<K, the forward reaction is favored? Is it because there are more reactants that will be turned into products as the reaction continues?

yes since there is more reactant more product will be formed.

Yes, that is true and when q>k, the reverse reaction is favored and there are more products, resulting in the production of reactants. However, I am having a hard time understanding why the value of Q matters when determining which direction a reaction will proceed.

To determine which direction a reaction will proceed, we have to calculate the reaction quotient (Q) at any time during reaction and compare it to K. If Q<K there are more reactants than products, therefore more products will be formed and the forward reaction is favored.

Yes, since Q and K are the same ratio ([products]/[reactants]) that means the [products] would have to decrease, or the [reactants] would have to increase, in order for Q to be less than K. Therefore, there will be more reactants yielding products so that the forward reaction is favored.
