How do I calculate Keq given the free energy change?

Cost-free Energy Scam or The Genuine Deal?:
Question by Gretchen: How do I calculate Keq given the cost-free power modify?
A reaction has a normal free of charge-energy modify of -20.00 kJ mol^-1. Calculate the equilibrium constant for the reaction at 25 degrees C.

I followed the guidelines I had and nonetheless got the wrong answer. What should I be undertaking?


Best answer:
Answer by schmiso∆G = -R∙T∙ln(K)

=>

K = e^ - ∆G/(R∙T)
= e^ - 20,000J/mol / (8.314472J/molK ∙ 298.15K)
