Chapter 16, Problem 38QAP

When permanganate ions in aqueous solution react with cobalt metal in strong acid, the equation for the reaction that takes place is

$2{\text{MnO}}_4{}^{-}\left(aq\right)+16{\text{H}}^{+}\left(aq\right)+5\text{Co}\left(s\right)\to 2{\text{Mn}}^{2+}\left(aq\right)+5{\text{CO}}^{2+}\left(aq\right)+8{\text{H}}_2\text{O}\left(l\right)$

$\Delta H°=-2024.6\text{kJ};\Delta G°$ at $\text{25}°\text{C}=-1750.9\text{kJ}$(a) Calculate ΔS° for the reaction at 25°C.

(b) Calculate S° for CO²⁺, given for S° is 30.04 J/mol $\cdot$
