The given reaction is CaCO3 = CaO + CO2. The Gibbs free energy change (ΔG) for this reaction is given by the equation ΔG = 177100 - 158T.

To find the calcination temperature of limestone, we need to set ΔG to zero because at equilibrium, the Gibbs free energy change is zero.

So, 0 = 177100 - 158T

Solving this equation for T (temperature), we get:

T = 177100 / 158 = 1121.52 K

So, the calcination temperature of limestone is approximately 1121.52 K.
