True or False
1.For the following reaction at equilibrium:
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â CaCO₃(s) â‡Œ CaO(s) + CO₂(g)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â increasing the total pressure by adding Ar(g) will shift theequilibrium to the left.
2.For the following reaction at equilibrium:
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â H₂(g) + F₂(g) â‡Œ 2HF(g)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â removing H₂ will increase the amount of F₂present once equilibrium is reestablished.
3.Increasing the temperature of an exothermic reaction shiftsthe equilibrium position to the right.
4.For the following reaction at equilibrium:
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â CaCO₃(s) â‡Œ CaO(s) + CO₂(g)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â adding more CaCO₃ will shift the equilibrium to theleft.
5. For the following reaction at equilibrium:
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2 H₂(g) + O₂(g)â‡Œ 2 H₂O(g)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â the equilibrium will shift to the left if the volume is halved.
