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. 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: 2 H2 (g) + O2 (g) ⇌ 2 H2O (g) the equilibrium will shift to the left if the volume is doubled. For the following reaction at equilibrium: H2 (g) + F2 (g) ⇌ 2HF (g) removing H2 will increase the amount of F2 present once equilibrium is reestablished. Increasing the temperature of an endothermic reaction shifts the equilibrium position to the right.
