Enthalpy and entropy changes of a reaction are 40.63kJmol^(-1) and 108

1.	Enthalpy and entropy changes of a reaction are 40.63kJmol^(-1) and 108 J K^(-1) mol^(-1) respectively . Predict the feasibility of the reaction at 27^(@)C
Answer» Solution :Here, we are given `: Delta H =40.63 kJ mol^(-1)= 40630 J mol^(-1) , Delta S = 108 J K^(-1) mol^(-1)` `T = 27^(@) C = 27 +273 =300K` `:. Delta G =Delta H = T Delta S = 40630 J mol^(-1) - 300 K xx 108.8 JK^(-1) mol^(-1) = 7990 J mol^(-1)` Since `Delta G` comes out to be positive ( i.e., ` Delta Ggt 0)` , the reaction is not feasible in the FORWARD DIRECTION.
