For this problem, use the concept of Hess's Law to find the Kc of the desired equation

Configuring each equation:

a)  M(g) ⇌ Z(g)   Kc1 = 3.1    →  Reverse then multiply the equation by 2. This will take the reciprocal then square of Kc

2 Z (g) ⇋ 2 M (g) Kc1-rev = (1/3.1)2 = 0.1041


b) 6 R(g) ⇌ 2 N(g) + 4 Z(g) Kc2 = 0.531 → Divide the equation by 2. This will take the square root of Kc

3 R(g) ⇌ N(g) + 2 Z(g) Kc2 = 0.531 =  (0.531)1/2 = 0.729
