Solution: At 900ºC, Kp = 1.04 for the reaction CaCO3(s) ⇌ CaO(s) + CO2(g)At a low temperature, dry ice (solid CO 2), calcium oxide, and calcium carbonate are introduced into a 50.0-L reaction chamber. The temperature is raised to 900ºC, 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 900ºC? b. 780 g CaCO3, 1.00 g CaO, PCO2 = 1.04 atm

Problem

At 900ºC, Kp = 1.04 for the reaction 

CaCO3(s) ⇌ CaO(s) + CO2(g)

At a low temperature, dry ice (solid CO 2), calcium oxide, and calcium carbonate are introduced into a 50.0-L reaction chamber. The temperature is raised to 900ºC, 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 900ºC?
