A) Exothermic and increasing disorder
B) Exothermic and decreasing disorder
C) Endothermic and increasing disorder
D) Endothermic and decreasing disorder
Correct Answer: A
Solution :
[a] Measure of disorder of a system is nothing but entropy. For a spontaneous reaction, \[\Delta G<0\]. As per Gibbs Helmholtz equation, \[\Delta G=\Delta H-T\Delta S\] Thus \[\Delta G\]is \[-ve\] only when \[\Delta H=-ve\](exothermic) and \[\Delta S=+ve\] (increasing disorder)You need to login to perform this action.
