Which of the following pairs of a chemical reaction is certain to result in a spontaneous reaction
Options
(a) exothermic and increasing disorder
(b) exothermic and decreasing disorder
(c) endothermic and increasing disorder
(d) endothermic and decreasing disorder
Correct Answer:
exothermic and increasing disorder
Explanation:
For spontaneous reaction ΔH = -ve, ΔS = +ve. Spontaneity depends upon both critical minimum energy and maximum randomness / disorder.
