Chapter 6, Problem 6B.8AE

Interpretation Introduction

Interpretation:

The temperature at which the equilibrium constant for decomposition of ${\text{CaCO}}_{\text{3}}$ to $\text{CaO}$ and ${\text{CO}}_{\text{2}}$ becomes $1$ has to be calculated.

Concept introduction:

Enthalpy is the internal heat content of the system.  Under constant pressure, a system can do expansion work under the effect of energy supplied as heat known as enthalpy change of the system.
