For a reversible reaction at constant temperature the reaction quotient is found to be greater than the equilibrium constant (Q>K). Which statement is correct?
AThe net reaction proceeds forward until Q rises to K
BThe value of K increases until it equals Q
CThe system is at equilibrium
DThe net reaction proceeds backward until Q falls to K
Answer: D
If Q>K there is more product (relative to reactant) than at equilibrium. The net change is therefore backward, which lowers Q until Q=K. The value of K itself depends only on temperature and does not change.
