Chapter 18, Problem 18.20QP

Given the following information at 25°C, calculate ΔG° at 25°C for the reaction

$2\text{A}(g)+\text{B}(g)\stackrel{}{\to }3\text{C}(g)$

Substance	$\Delta H_f^{°}$(kJ/mol)	S°(J/mol·K)
A(g)	191	244
B(g)	70.8	300
C(g)	−197	164

1. a −956 kJ
2. b 956 kJ
3. c −346 kJ
4. d 346 kJ
5. e −1.03 × 10³ kJ
