Part 1B Continued
4.
Consider the reaction:
2 H2S (g) 2 H2 (g) + S2 (g) K, = 2.4 10-4 at 1073 K
A reaction mixture contains 0.112 atm of H2, 0.055 atm of S2, and 0.445 atm of H2S. Is the reaction mixture at
equilibrium? If not, in what direction will the reaction proceed?
5. Consider the reaction:
CO (g) + 2 H2 (g) → CH30H (g) at 298 K
An equilibrium mixture of this reaction at a certain temperature has [CO] = 0.105 M, [H2] = 0.144 M and [CH3OH] = 0.18
M. What is the value of the equilibrium constant (K) at this temperature? What is the value of K,?
6. Nitrogen dioxide dimerizes according to the reaction:
2 NO2 (g) N204 (g) Kp = 6.7 at 298 K
A 2.25-L container contains 0.055 mol of NO2 and 0.082 mol of N204 at 298 K. Is the reaction at equilibrium? If not, in
what direction will the reaction proceed?
