Principles of Chemistry II: Chemical Equilibrium

answer the following questions. Please show all of your work for calculations.

1. In the following reaction: 2NO(g) + H2(g) ⇌ N2O(g) + H2O(g) ΔH° = -22 kJ/mol

in which direction, left or right, will the equilibrium shift if the following changes are made? How will the equilibrium constant Kc change (increase, decrease, or keep same)?

Disturbance	Shift of equilibrium	Change of Kc
NO is added
H2 is removed
N2O is added
Pressure is increased
Volume is increased
the system is cooled
Argon is added at constant volume
Argon is added at constant pressure
Catalyst is added

2. In the following reaction: 2NOCl(g) ⇌ 2NO(g) + Cl2(g), the equilibrium constant Kc = 4.0×10-4.

(a) What is the state of the system if [NOCl] = 2.0 M, [NO] = 0.10 M, and [Cl2] = 0.10 M? (at equilibrium, produce more products, or produce more reactants)

(b) What are the equilibrium concentrations of NOCl, NO, and Cl2?
