Chemical Equilibrium

Consider the general reaction given below at 400 K
xA(g)⇌yB(g).
The values of Kp and Kc are studied under the same condition of temperature but variation in x and y.
(i) Kp=85.87 and Kc=2.586 appropriate units
(ii) Kp=0.862 and Kc=28.62 appropriate units
The values of x and y in (i) and (ii) respectively are:
