Do we need a constant pressure or temperature to use the Vant Hoff equation?

You need a constant pressure. The Van't Hoff equation can be used to calculate K @ different temperature if delta H is known.

Gibbs free energy changes with the temperature and pressure of the thermodynamic system. So the point of the van 't Hoff equation is that it relates the change in Keq to the change in temperature, T, when you are given delta H at a constant temperature.
