    For the homogeneous reactions: \[xA+yB\,\,\to \,\,\ell Y+mZ\] \[\Delta H=-30\text{ }kJ\text{ }mo{{l}^{-1}},\text{ }\Delta S=-100\text{ }J{{k}^{-}}^{1}\,mo{{l}^{-1}}\] At what temperature the reaction is at equilibrium?

    A) \[50{}^\circ C\]                        

    B) \[250{}^\circ C\]

    C) \[100\text{ }K\]             

    D) \[27{}^\circ C\]

    Correct Answer: D

    Solution :

    \[\Delta G=\Delta H-T\Delta S\] At equilibrium \[\Delta G\,\,=\,\,0\] \[T=\frac{\Delta H}{\Delta S}\]
