Consider the decomposition equilibrium CaCO3(s)⇌CaO(s)+CO2(g).\text{CaCO}_3(s) \rightleftharpoons \text{CaO}(s)+\text{CO}_2(g). Which of the following species appears in the expression for KpK_p for this equilibrium? a) CaCO3(s)\text{CaCO}_3(s) b) CaCO3(s) and CaO(s)\text{CaCO}_3(s)\text{ and }\text{CaO}(s) c) CO2(g)\text{CO}_2(g) d) CaCO3(s), CaO(s), and CO2(g)\text{CaCO}_3(s),\ \text{CaO}(s),\ \text{and }\text{CO}_2(g)
