Answer to Question #145135 in General Chemistry for sonya moyer

Question

a. (10 points) The equilibrium constant Kp for the following reaction is 6.2 x 10-5 at 100 K.

4 H2Se (g) ⇌ 4 H2 (g) + Se4 (g)

If an equilibrium mixture contains 12.5 atm H2Se and 0.25 atm H2, what is the concentration of Se4 at equilibrium?

b. (10 points) Consider the following equilibrium process:

2 H2O (l) ⇌ 2 H2 (g) + O2 (g) ∆H = 129.5 kJ

Predict the direction of the shift in equilibrium when the following changes are made:

The temperature is increased
More hydrogen gas is added
Some H2O is removed from the reaction mixture
Oxygen gas is removed
The pressure was increased
