Equilibria Changes

[Beatrice Petelo 1F]

Why does the value of K not change when we change the concentration of reactants or products?

[Zenita Leang 2K]

Changing the concentration of reactants or products will change the reaction quotient, the Q, of a reaction. The K doesn't change because there is a specific equilibrium constant, K, for each reaction at given temperatures. When you change the concentration of a reaction or a product, the reaction will try to readjust and bring itself back to K.

[Irene Zhou 1E]

Changing the concentration of reactants or products will not change the K value because the change will either result in more reactants or products being formed to bring the reaction back to equilibrium.

[Julia Lung 1I]

You would use the initial concentration mostly for the ICE table
