The correct thermodynamic conditions for the spontaneous reaction...

The correct thermodynamic conditions for the spontaneous reaction at all temperatures is:

Options

  1. A∆H<0∆ H < 0 and ∆S=0∆ S = 0
  2. B∆H>0∆ H > 0 and ∆S<0∆ S < 0
  3. C∆H<0∆ H < 0 and ∆S>0∆ S > 0
  4. D∆H<0∆ H < 0 and ∆S<0∆ S < 0

Correct answer

C. ∆H<0∆ H < 0 and ∆S>0∆ S > 0

Step-by-step solution

∆G=∆H−T∆S∆ G = ∆ H - T ∆ S

for spontaneous reaction \DeltaG<0\DeltaG < 0

Hence for Spontaneous reaction at all temperature ∆H<0,∆S>0∆ H < 0, ∆ S > 0
