following processes can take place at 298 K without violating the Second Law of
Thermodynamics?
(a) AH = -84 kJ mol" (-20 kcal mol"),
AS = +125 J mol"'K-'(+30 cal mol'K-')
(b) AH = -84 kJ mol (-20 kcal mol-'),
AS = -125 J mol-'K-'(-30 cal mol'K-)
(c) AH = +84 kJ mol- (+20 kcal mol-),
AS = -125 J mol-'K-'(+30 cal mol-'K-)
(d) AH = +84 kJ mol- (+20 kcal mol-),
AS = -125 J mol'K-'(-30 cal mol K-)
