### Different Constants of Eqn

Would we use the original Van't Hoff Equation: lnK=-$\frac{\Delta H°}{RT}+\frac{\Delta S°}{R}$ for constant temperatures?

Yes, we need a constant temperature to use that equation.

Yes, T is constant. In general if there it is a delta change or a ratio of T there is a change in temperature, but if it is just T temperature is constant.

To add, when the equation is derived, delta g is assumed to be zero since the system is at equilibrium
