13.4 Exercise 32

Avg difficulty 2.5

What is the minimum mass of CaCO3 required to establish equilibrium at a certain temperature in a 6.50-L container if the equilibrium constant (Kc) is 0.50 for the decomposition reaction of CaCO3 at that temperature?

CaCO3(s)⇌CaO(s)+CO2(g)\text{CaCO}_{3} \left(s\right) \rightleftharpoons \text{CaO} \left(s\right) + \text{CO}_{2} \left(g\right)
