I found out you can use the Arrhenius equation. However, i am confused on how Ea=deltah. Can someone explain that to me?

No, you can't use Arrhenius equation, it is not about kinetics. You need an equation that combines equilibrium constant with thermodynamic parameters of the reaction.

thanks i found the right equation, what was really confusing me what how similar the equations were. But after deriving the equation, it turned out to be pure coincidence
