NEET2016ChemistryThermodynamics (C)Actual
The correct thermodynamic conditions for the spontaneous reaction at all temperatures is:
Options
- A∆ H < 0 and ∆ S = 0
- B∆ H > 0 and ∆ S < 0
- C∆ H < 0 and ∆ S > 0
- D∆ H < 0 and ∆ S < 0
Correct answer
C. ∆ H < 0 and ∆ S > 0
Step-by-step solution
∆ G = ∆ H - T ∆ S for spontaneous reaction Δ G < 0 Hence for Spontaneous reaction at all temperature ∆ H < 0 , ∆ S > 0
