QNEET-2016-Ch-1014: NEET 2016 Chemistry - Class 11 NEET-2016-Ch-1014 Solution: The correct thermodynamic conditions for the spontaneous…

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

\Delta H < 0

and

\Delta S > 0

\Delta H < 0

and

\Delta S < 0

\Delta H < 0

and

\Delta S = 0

\Delta H > 0

and

\Delta S < 0

Multiple Choice Options

A $\Delta$ _ H < 0 and $\Delta$ _ S > 0
B $\Delta$ _ H < 0 and $\Delta$ _ S < 0
C $\Delta$ _ H < 0 and $\Delta$ _ S = 0
D $\Delta$ _ H > 0 and $\Delta$ _ S < 0

Step-by-Step Verified Solution

_ G = _ H _ T _ S If _ H < 0 and _ S > 0 _ G = ( _ v e ) _ T ( + v e ) then at all temperatures, _ G = -ve, spontaneous reaction. If _ H < 0 and _ S = 0 _ G = ( _ v e ) _ T ( 0 ) then at all temperatures, _ G = -ve at all temperatures.
