For a particular reversible reaciton at temperature `T, DeltaH` and `DeltaS` were found to be both `+ve`. If `T_e` is the temperature at equilibrium, the reaciton would be spontaneous when :A. `T_(e)gtT`B. `TgtT_(e)`C. `T_(e)` is `5` times `T`D. `T=T_(e)`

Answer» Correct Answer - b
`DeltaG=DeltaH-TDeltaS`
at equilibrium, `DeltaG=0` so, `TDeltaS=DeltaH`
As `DeltaH` and `DeltaS` are `+ve`, for a reaction to be spontaneous `DeltaG` should be -ve.
`TDeltaSgtDeltaH i.e,. TDeltaSgtT_(e)DeltaS`
`:. TgtT_(e)`
