Question

Adding reactant to a system at equilibrium makes the quotient smaller than K, so the equilibrium:

Accepted Answer

C. Shifts to the right

1. Adding reactant increases the denominator of the reaction quotient.
2. If reactant is added, or product is removed, then the quotient becomes less than the constant.
3. In that case the equilibrium will shift right.
4. Note the constant itself does not change, only the composition does.
