Which of the following are true statements about equilibrium systems? True False

Question

Which of the following are true statements about equilibrium systems?

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

True False  For the following reaction at equilibrium:
                       2 H2(g) + O2(g) 2 H2O(g)
                       the equilibrium will shift to the right if the volume is doubled.

True False  For the following reaction at equilibrium:
                       H2(g) + F2(g) 2HF(g)
                       removing H2 will have no effect on the amount of F2 present once equilibrium is reestablished.

True False  For the following reaction at equilibrium:
                       CaCO3(s) CaO(s) + CO2(g)
                       increasing the total pressure by adding Ar(g) will have no effect on the equilibrium position.

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

Explanation / Answer

1) false (since adding CaCO3 equilibrium doesnot alter)

2) False (Increasing the volume of the container will decrease the pressure of system so  the equilibrium will shift to the right since there are more moles of gas on the right and that will make for a greater pressure)

3) False (removing H2 equilibrium shifts left since moles of reactants decreases as a result moles of F2 increases)

4) True
