Calculate the standard entropy change for the reactionXhArrYif the val

1.	Calculate the standard entropy change for the reactionXhArrYif the value of Delta H^(@) = 28.40kJ andequilibrium constant is 1.8 xx 10^(-7)at 298 K
Answer» Solution :`Delta_(r)G^(@) = - 2.303 RT log K = + 38484J` `Delta_(r) G^(@) = Delta_(r)H^(@) - T DeltaS ^(@) , i.e., Delta_(r) S^(@) = ( Delta_(r)H^(@) - Delta_(r)G^(@))/(T)= ( 28400-38484)/(298) = -33.8 J K^(-1) mol^(-1)`
