Problem
For a reaction at 298 K, the standard enthalpy change is +45 kJ·mol⁻¹ and the standard entropy change is +140 J·mol⁻¹·K⁻¹.
Is the equilibrium constant at 298 K expected to be greater than 1, equal to 1, or less than 1? Briefly justify your prediction based on the signs of the thermodynamic quantities.
