Question

Which of the following are true statements about equilibrium systems?

True/False 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.

True/False 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.

True/False For the following reaction at equilibrium:
                       CaCO₃(s) ⇌ CaO(s) + CO₂(g)
                       adding more CaCO₃ will shift the equilibrium to the right.

True/False Increasing the temperature of an exothermic reaction shifts the equilibrium position to the right.

True/False 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.

Answer 1

True/False 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. IF we double Volume we decrease P. If we decrease P we favour more mol formation. Then the fhist goes to LEFT. This is TRUe

True/False 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. FAlse, since the shift will shit toward reactants to form H2 and F2

True/False For the following reaction at equilibrium:
                       CaCO3(s) ⇌ CaO(s) + CO2(g)
                       adding more CaCO3 will shift the equilibrium to the right. true, since increase in reagents increases production

True/False Increasing the temperature of an exothermic reaction shifts the equilibrium position to the right.

True/False 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. false, will shift it to the left since there ar eno mole formation.
