Assignment:
For the equilibrium system
CO2(g) + H2(g) CO(g) + H2O(g) H = +42 kJ/mol
K equals 1.6 at 1260 K. If 0.15 mol each of CO2, H2, CO, and H2O (all at 1260 K) were placed in a 1.0-L thermally insulated vessel that was also at 1260 K, then when the system came to equilibrium,
A) the temperature would remain constant and the mass of CO2 would increase.
B) the temperature would decrease and the mass of CO2 would decrease.
C) the temperature would increase and the mass of CO2 would decrease.
D) the temperature would decrease and the mass of CO2 would increase.
E) the temperature would increase and the mass of CO2 would increase.
