Solution

Dear student
The reaction of ammonia formation (forward reaction):
N_2(g)+ 3H_2(g)------->2NH_3(g)
and the reaction for ammonia decomposition is (backward reaction):
2NH₃_(g) ---------> N_2(g)+ 3H_2(g)
Given, Kp for forward reaction = 6.810⁵
So, Kp for backward reaction is = 1/6.810⁵ = 1.47 * 10^-6
