Question

Given the following values for the changes in enthalpy (∆H) and entropy (∆S), which of the following processes can take place at 298 K without violating the Second Law ofThermodynamics? Calculate the following.

(a) AH = -84 kJ mol (-20 kcal mol),
AS = +125 J mol- K- (+30 cal mol'K-1)
(b) AH = -84 kJ mol- (-20 kcal mol-1),
AS = -125 J mol¬1 K-1 (-30 cal mol- K-1)
(c) AH = +84 kJ mol- (+20 kcal mol-1),
AS = -125 J mol-'K- (+30 cal mol- K-')
(d) AH = +84 kJ mol- (+20 kcal mol-1),
AS = -125 J mol¬ K-' (-30 cal mol- K-1)
