For a particular reversible reaction at temperature T, ∆H and ∆S were found to be both +ve. If Te is the temperature at equilibrium, the reaction would be spontaneous when :

Multiple Choice Options

  • A Te > T
  • B T > Te
  • C Te is 5 times T
  • D T = Te

Step-by-Step Verified Solution

At equilibrium ΔG=0

Hence, ΔG=ΔH−TeΔS=0

∴ ΔH=TeΔS

or Te=ΔHΔS

For a spontaneous reaction

ΔG must be negative

which is possible only if ΔH<TΔS

or T>ΔHΔS;Te<T
