Vedclass · Answer

(D) The Gibbs free energy change is given by the equation: $ \Delta G = \Delta H - T \Delta S $. For a process to be spontaneous,the value of $ \Delta G $ must be negative $( \Delta G If $ \Delta H $ is negative $( -ve )$ and $ T \Delta S $ is positive $( +ve )$,then $ \Delta G = (-ve) - (+ve) = -ve $. This condition ensures that $ \Delta G $ is always negative at any temperature,thereby favouring the reduction of a metal oxide to metal.
