1. The problem statement, all variables and given/known data The water gas shift reaction used commercially to produce H2 deltaG std condtions = -28.6 KJ\mol Calculate the Kp at 900K 2. Relevant equations G0=-RTln(k) 3. The attempt at a solution -28.6x1000/(-8.314x900)= ln(k) k=e3.822 k= 45.7 However this is not the correct answer. COuld someone please help me out.
