Equilibrium constants vs equilibrium of the P&R

Postby 205192823 » Mon Jan 20, 2020 8:30 pm

I understand that the equilibrium constant is Kc or just K, but what does it mean when it is asking about the equilibrium constant of the products? For example it asks," if one starts with higher concentrations of reactants, the equilibrium concentrations of the products will be larger". I'm a little confused on what this question is asking.

The equilibrium constant will only change when there is a change in the temperature. Otherwise, the Kc does not change, only the Q will change.

This is asking how will a reaction shift if we start with more reactants. You can think of it as the reaction quotient Q. If we start with more reactants, Q will be smaller than k and therefore the reaction will shift to the right to produce more products.

It is asking whether the concentration of the products when the reaction is at equilibrium will be higher when more of the reactants are added to the reaction.
