A reaction will never the spontaneous at any temperature and pressure if

Options

A. `DeltaS =+ve, DeltaH =+ve`
B. `DeltaS =+ve, DeltaH =- ve`
C. `DeltaS =- ve, DeltaH =+ve`
D. `DeltaS =-ve, DeltaH =- ve`

Explanation

To determine the conditions under which a reaction will never be spontaneous at any temperature and pressure, we need to analyze the Gibbs free energy change (ΔG) for the reaction. The spontaneity of a reaction is determined by the sign of ΔG, where:

- A reaction is spontaneous if ΔG < 0 (negative).
- A reaction is non-spontaneous if ΔG > 0 (positive).
