Which of the following are true statements about equilibriumsystems?

Options: True or False

a) For the following reaction at equilibrium:
2 H2(g) + O2(g) ? 2 H2O(g)
the equilibrium will shift to the right if the volume isdoubled.

b) For the following reaction at equilibrium:
H2(g) + F2(g) ? 2HF(g)
removing H2 will increase the amount of F2present once equilibrium is reestablished.

c) For the following reaction at equilibrium:
CaCO3(s) ? CaO(s) + CO2(g)
increasing the total pressure by adding Ar(g) will shift theequilibrium to the left.

d) For the following reaction at equilibrium:
CaCO3(s) ? CaO(s) + CO2(g)
adding more CaCO3 will shift the equilibrium to theleft.

e) Increasing the temperature of an endothermic reaction shiftsthe equilibrium position to the left.
