Vedclass · Answer

(B) The change in entropy,$\Delta S$,is related to the change in the number of moles of gaseous species $(\Delta n_g)$.$A$. $\Delta n_g = 0 - 0.5 = -0.5$$B$. $\Delta n_g = 1 - 0 = +1$$C$. $\Delta n_g = 1 - 1 = 0$$D$. $\Delta n_g = 2 - 2 = 0$Since reaction $B$ involves the production of a gas from a solid,it results in the largest increase in disorder,making $\Delta S$ maximum.

For which of the following reactions will $\Delta S$ be maximum?
