Chapter 14, Problem 14.1KSP

Using $\Delta G_{\text{f}}°$ values from Appendix 2, calculate the standard free-energy change $(\Delta G{°}_{\text{rxn}})$ of the following reaction at 25.0°C.

${\text{Mg(OH)}}_{\text{2}}(s)\to \text{MgO(}s{\text{) + H}}_{\text{2}}\text{O(}l\text{)}$

(a) − 35.6 kJ/mol

(b) − 1166.2 kJ/mol

(c) + 35.6 kJ/mol

(d) + 1166.2 kJ/mol

(e) + 27.0 kJ/mol
