For the endothermic reaction:

2 H2O(g) <--> 2 H2(g) + O2(g)


indicate in which direction the equilibrium shifts when the following stresses are applied to the system or if there is no change in equilibrium.

A. Hydrogen is added to the system.

B. The partial pressure of water is increased.

C. Oxygen is removed from the system.

D. The temperature is increased.

E. The volume of the container is decreased.

F. A catalyst is added.

G. Helium is added at constant volume.

H. Argon gas is added at constant pressure.

Homework Answers

Answer #1

A. If hydrogen is added to the system then the equilibrium shifts towards reactant side.

B. If partial partial pressure of H2O is increased then the equilibrium shifts towards the side having fewer gas molecules. hence the reaction shifts towards reactant side.

C. If oxygen is removed from the system then the equilibrium shifts towards product side.

D. If temperature of the system is increased then the equilibrium shifts towards the Endo direction that is towards the product side.

E. If volume of the container decreases then the equilibrium shifts towards fewer gas molecules that is to the reactant side.

F. If a catalyst is added then no shift occur.
