Determinewhetherthe reactionN_(2) O_(4(g)) to2NO_(2(g)) isspontaneous at 25^(@)C from thefollowingdata : Delta_(f)H_((N_(2)O_(4)))^(@) =9.16 kJ mol^(-1) Delta_(f)H_((NO_(2)))^(@) = 33.2 kJ mol^(-1) S_((N_(2)O_(4)))^(@) = 304.2 JK^(-1)mol^(-1)S_(NO_(2))^(@)= 240JK^(-1) mol^(-1) At whattemperaturewill the reactionbecomespontaneous ? |
