Vedclass · Answer

(B) According to Gibbs' energy equation,$ \Delta G = \Delta H - T \Delta S $. For a process to be spontaneous,$ \Delta G $ must be negative. When $ \Delta H $ is negative (exothermic) and $ \Delta S $ is positive (increase in entropy),the term $ -T \Delta S $ becomes negative. Thus,$ \Delta G = (	ext{negative}) - (	ext{positive}) = 	ext{negative}$. Therefore,the process is spontaneous at all temperatures when $ \Delta H  0 $.
