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?

Options

A. Reaction I
B. Reaction II
C. Reaction III
D. Reaction IV

Answer

D

Explanation

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.
