1. The problem statement, all variables and given/known data If Kp = 6.0 x 108 For equilibrium N2 <--> 2N Then what is the equilibrium constant of N <--> .5N2 2. Relevant equations K= C^c/A^a 3. The attempt at a solution I tried finding the fourth root of 6.0 x 108 and that didn't give the right result. BTW the answer is 4.1 x 103, I'm just looking for the way to solve the problem.
