Which of the following pairs of a chemical reaction is certaion to result a spontaneous reaction ?

Options

A. Exothermic and decreasing disorder
B. Endothermic and increasing disorder
C. Exothermic and increasing disorder
D. Endothermic and decreasing disorder

Answer

C

Explanation

`Delta G= Delta H- T Delta S`
For spontaneous process `Delta G` should be negative in option (c) `Delta H` = -ve and `Delta S`= +ve than `Delta S= (-ve) - T(+ve) = -ve`
