Chapter 18, Problem 18.7P

Calculate the value of $\Delta {\text{S}}_{\text{total,}}$ and decide whether the decomposition of calcium carbonate is spontaneous under standard-state conditions at 25^oC (Hint: Look up values of $\Delta {\text{H}}^{\text{o}}{}_{\text{f,}}$ and $\Delta {\text{S}}^{\text{o}}$ for each reactant and product in Appendix B.)
