A reaction has value of `Delta H = -40 kcal mol^(-1)` at 400 K. Below 400 K the reaction is spontaneous and above 400 K it is not. The value of `DeltaG` and `Delta S` at 400 K are respectively

A

`0, -0.1 cal K ^(-1) mol ^(-1)`

B

`0, 100 cal K ^(-1) mol ^(-1)`

C

`10 kcal mol ^(-1), - 100 cal K ^(-1) mol ^(-1)`

D

`0, -100 cal K ^(-1) mol ^(-1)`
