$Q$ vs. $K$

APCHEM-9WLAGV

Consider the reaction quotient, $Q$, for a typical chemical system.

Which of the following INCORRECTLY describes the relationship between the value of $Q$ and the equilibrium constant, $K$?

A

If $Q$ is greater than $K$ ($Q > K$), the system will shift to increase the concentration(s) of reactant(s).

B

If $Q$ is less than $K$ ($Q < K$), the system will shift to increase the concentration(s) of reactant(s).

C

If $Q$ equals $K$ ($Q=K$), the system is at equilibrium.

D

If $Q$ equals $K$ ($Q=K$), the concentration(s) of reactant(s) and product(s) will be constant over time.
