Reaction Quotient

Postby Harjot Manku 1C » Sun Jul 30, 2017 10:23 pm

What are the differences between Equilibrium Constant (K) and the Reaction Quotient (Q)?

The reaction quotient (Q) is similar to the equilibrium constant (K), but K is the constant when the reaction is in equilibrium while Q is for any stage of the reaction except when it is at equilibrium.

For extension the value of K can't be influenced by the concentration of reactant or production but temperature, while Q is calculated from the current concentration of reactant and production.

By comparing Q to K, it will tell you whether the reaction will proceed forward, backward, or is already at equilibrium
If Q = K, then the reaction is at equilibrium
If Q < K, then the reaction will favor the products (proceeds forward)
If Q > K, then the reaction will favor the reactants (proceeds backward)
