For a reaction to occur spontaneously

Options

A. `T Delta S lt Delta H` and both `Delta H and Delta S` are +ve
B. `T Delta S gt Delta H` and `Delta H` is +ve and `Delta S` is -ve
C. `T Delta S gt Delta H` and both `Delta H and Delta S` are +ve
D. `T Delta S = Delta H` and both `Delta H and Delta S` are +ve

Answer

C

Explanation

For spontaneous reaction :
`Delta G (- ve), Delta S = + ve, Delta H = + ve and T Delta S gt Delta H`
