The value of `Delta H` and `Delta S` for five different reaction are given below. `|{:("Reaction",Delta H(kJ mol^(-)),Delta S(JK^(-)mol^(-))),(I,+98.0,+14.8),(II,+55.5,+14.8),(III,+28.3,-84.8),(IV,-40.5,+24.6),(V,+34.7," 0.0"):}|` On the basis of these values,k predict whihc one of these will be spontaneous at all temperature?A. Reaction IB. Reaction IIC. Reaction IIID. Reaction IV |

Answer» Correct Answer - D According to thermodynamics, `Delta G = Delta H = T Delta S` If `Delta H` is negative and `Delta S` is positive, then `Delta G` will always be negative regardless of the temperature. |
