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, predict which 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

A spontaneous process is accompanied by decrease in enthalpy and increase in entropy means `Delta H` is negative and `Delta S` is positive.
