The reaction of hydroxide ion with chloromethane to yield methanol and chloride ion is an example of a general reaction type called a nucleophilic substitution reaction: HO + CH;CI = CH;OH + CI The value of AH° for the reaction is -75 kJ/mol, and the value of AS° is +54 J/ (K- mol). What is the value of AG° (in kJ/mol) at 298 K? Is the reaction exothermic or endothermic? Is it exergonic or endergonic?

You may want to reference (Pages 187 - 190) Section 5.7 while completing this problem.
