Question

At 900°c, Kp = 1.04 for the reaction

CaCO3 (s) ⇌ CaO (s) + CO2 (g)

At a low temperature, dry ice (solid CO2), calcium oxide, and calcium carbonate areintroduced into a 50.0-L reaction chamber. The temperature is raised to 900°c, resulting in the dry ice converting to gaseous CO2 . For the following mixtures, will the initial amount of calcium oxide increase, decrease, or remain the same as the system moves toward equilibrium at 9000°C?

a) 655gCaCo3, 95.0gCaO, PCO2 = 2.55atm

b) 780gCaCo3, 1.00gCaO, PCO2 = 1.04atm

c) 0.14gCaCo3, 5000gCaO, PCO2 = 1.04atm

d) 715gCaCo3, 813gCaO, PCO2 = 0.211atm
