The correct thermodnamic conditions for ...

The correct thermodnamic conditions for the spontaneous reaction at all temperature is:

A

`DeltaHlt0` and `DeltaSlt0`

B

`DeltaHlt0` and `DeltaS=0`

C

`DeltaHgt0` and `DeltaSlt0`

D

`DeltaHlt0` and `DeltaSgt0`

Text Solution

Verified by Experts

The correct Answer is:
C

`DeltaG=DeltaH-TDeltaS`
For spontaneous process `(DeltaG=-ve)` at all temperature, `DeltaHlt0` and `DeltaSgt0` are favourable factors
`DeltaG=DeltaH-TDeltaS=(-ve)-T(+ve)`
