We're being asked to identify which of the following statements regarding equilibrium is/are correct.

I. If Q > Keq, the reaction must shift toward reactants to be at equilibrium
II. A reversible reaction is at equilibrium when the rates of forward and reverse reactions are equal
III. For the reaction CaO(s) + CO2(g) ⇌ CaCO3(s), Kp has units of atm
-1


Let's analyze each statement given:

I. If Q > Keq, the reaction must shift toward reactants to be at equilibrium

Depending on if Q is greater than or less than K our reaction will shift to attain equilibrium by reaching the equilibrium constant K:
