Le Chatelier's Principle III Which of the following are true statements about equilibrium systems? For the following reaction at equilibrium: CaCO3(s)=CaO(s)+CO2(g) adding more CaCO3 will shift the equilibrium to the right. Increasing the temperature of an exothermic reaction shifts the equilibrium position to the left. For the following reaction at equilibrium: H2(g)+F2(g)=2HF(g) removing H2 will decrease the amount of F2 present once equilibrium is reestablished. For the following reaction at equilibrium: CaCO3(s)=CaO(s)+CO2(g) increasing the total pressure by adding Ar(g) will shift the equilibrium to the right. For the following reaction at equilibrium: 2H2(g)+O2(g)=2H2O(g) the equilibrium will shift to the left if the volume is doubled
