Homework Answers

Answer #1

C(s) + H2O(g) ↔ CO(g) + H2(g ΔH°rxn = +131 kJ.

forward reaction is endothermic reaction.

a) An increase in the reaction temperature.

The temperature is increases the equilibrium shift to forward direction.

b) A decrease in the amount of C(s).

conc of reactants are decreases the equilibrium shift to reverse direction. So conc of C decreases the equilibrium shift to reverse direction.

c) A decrease in the reactor volume.

The equilibrium shift to reverse direction.

d) An increase in PH2O.

The pressure increases the volume or no of moles decreases side shift the equilibrium.

PH2O increases the equilibrium shift to reverse direction.

e.Addition of N2 gas to the reaction mixture.

The equilibrium shift to forward direction
