(B) For a process to be spontaneous,the change in Gibbs free energy must be negative,i.e.,$\Delta G We use the Gibbs-Helmholtz equation: $\Delta G = \Delta H - T\Delta S$.For the process to be spontaneous at all temperatures $(T)$,the term $\Delta G$ must remain negative regardless of the value of $T$.If $\Delta H  0$ (increase in entropy),then $\Delta G = (	ext{negative}) - T(	ext{positive})$.Since $T$ is always positive in Kelvin,$\Delta G$ will always be negative at all temperatures.
