Question

Write the value of K and K equation for CaCO₃(s) ⇌ CaO(s) + CO₂(g)

Answer 1

A pure solid always has the same concentration at a given temperature, as it does not expand to fill its container i.e., it has the same no. of moles of its volume. Therefore the concentration of pure solid is a constant. So the expression if K and K is K [CO₂], K = \(P_{CO_2}\)
