Problem

For a particular reaction,

\Delta H^\circ=-125\,\text{kJ}\cdot\text{mol}^{-1}

and

\Delta S^\circ=-250\,\text{J}\cdot\text{mol}^{-1}\cdot\text{K}^{-1}

. Determine the temperature (in kelvin) at which the reaction becomes thermodynamically indifferent, i.e., the equilibrium constant equals 1.
