For each reaction below, indicate in which direction the equilibrium shifts when the stated stress is applied to the system. Write R if the reaction shifts to the right, L if the reaction shifts to the left, or NC if there is no change.
A. Reaction: PCl5(g) <==> PCl3(g) + Cl2 + heat
Stress: temperature increase
B. Reaction: CO(g) + Fe3O4(s) <==> CO2(g) + 3FeO(s)
Stress: volume. Increase
C. Reaction: C2H2(g) + H2O(g) <==> CH3CHO(g) + heat
Stress: temperature decrease
D. Reaction: 2NO(g) + H2(g) <==> N20(g) + H2O(g) + heat
Stress: volume decrease
E. Reaction: Heat + H2(g) + l2(g) <==> 2Hl(g)
Stress: temperature decrease
F: H2(g) + Cl2(g) <==> 2HCl(g) + heat
Stress: volume decrease
