Web20 jun. 2024 · Δ G o = − R T ln ( K) If we want to understand how the equilibrium constant will change we can rearrange this equation to solve for K and plot as a function of temperature. Doing this and making the substitution for the free energy Δ G o = Δ H o − T Δ S o gives. K = e − Δ H o R T + Δ S o R. Since the reaction is endothermic, Δ H o > 0.
