      For a particular reversible reaction at temperature T, \[\Delta H\] and\[\Delta S\]were found to be both +ve. If\[{{T}_{e}}\]is the temperature at equilibrium, the reaction would be spontaneous when       AIEEE  Solved  Paper-2010

    A) \[T={{T}_{e}}\]                 

    B) \[{{T}_{e}}>T\] 

    C)        \[T>{{T}_{e}}\] 

    D)        \[{{T}_{e}}\]is 5 times T

    Correct Answer: C

    Solution :

    \[\begin{align}   & \Delta G=\Delta H-T\Delta S \\  & \,\,\,\,\,\,\,\,\,\,\,\,\,+ve\,\,\,\,\,+ve \\ \end{align}\] \[T>{{T}_{e}}\]for \[\Delta G=-ve\]
