In which case,a spontaneous reaction is impossible at any temperature `[Delta H+ve,Delta S+ve]`, `[Delta H+ve,Delta S-ve]`, `[Delta H-ve,Delta S-ve]`, `[" in all cases "]`

In which of the following cases,the reaction is spontaneous at all temperature [A] Delta H>0,Delta S>0 ; [B] Delta H 0 ; [C] Delta H>0,Delta S<0

Delta S = Delta H//T holds good for

For the process H_(2)O(l)(" lbar ",373K)rarr H_(2)O(g) (l bar, 373K) the correct set of thermodynamic parameters is [" (A) "Delta G=0,Delta S=+ve] , [" (B) "Delta G=0,Delta S=-ve] [" (C )"Delta G=+ve,Delta S=0] , [" (D )"Delta G=-ve,Delta S=+ve]

A porcess is nonspontaneous at evey temperature if (i) Delta H gt 0, Delta S = 0 (ii) Delta H lt 0, Delta S gt 0 (iii) Delta H gt 0, Delta S lt 0 (iv) Delta H = 0, Delta S lt 0

Predict the sign of DeltaG for the reaction at a very low temperature for which DeltaH is +ve and DeltaS is positive.

For an exothermic reaction to be spontaneous ( Delta S = negative)
