Vedclass · Answer

(B) $1$. Calculate $\Delta n_g$: $\Delta n_g = 	ext{moles of gaseous products} - 	ext{moles of gaseous reactants} = 2 - (2 + 1) = -1 \ mol$. $2$. Calculate $\Delta H^o$: $\Delta H^o = \Delta U + \Delta n_g RT = -10.5 \ kJ + (-1 \ mol 	imes 8.314 	imes 10^{-3} \ kJ/K \cdot mol 	imes 298 \ K) = -10.5 - 2.477 = -12.977 \ kJ$. $3$. Calculate $\Delta G^o$: $\Delta G^o = \Delta H^o - T\Delta S^o = -12.977 \ kJ - (298 \ K 	imes -10.5 	imes 10^{-3} \ kJ/K) = -12.977 + 3.129 = -9.848 \ kJ$. $4$. Since $\Delta G^o < 0$,the reaction is spontaneous.

For the reaction $2X_{(g)} + Y_{(g)} \to 2Z_{(g)}$ at $298 \ K$,$\Delta U = -10.5 \ kJ$ and $\Delta S^o = -10.5 \ J/K$. Calculate $\Delta G^o$ for the reaction. Will the reaction be spontaneous or not? Explain.
