Explanation / Answer

2Cl2(g) + 2H2O(g) -----------> 4HCl(g) + O2(g)
Kp = [HCl]^4[O2]/[Cl2]^2[H2O]^2
part-A
4HCl(g) + O2(g) ----------> 2Cl2(g) + 2H2O(g)
Kp1   = [Cl2]^2[H2O]^2/[HCl]^4[O2]
1/Kp   = [HCl]^4[O2]/[Cl2]^2[H2O]^2
KP1    = 1/Kp
KP1       = 1/7.53*10^-2
13.3    = [HCl]^4[O2]/[Cl2]^2[H2O]^2

KP1   = 13.3

part-B
2Cl2(g) + 2H2O(g) -----------> 4HCl(g) + O2(g)
Kp = [HCl]^4[O2]/[Cl2]^2[H2O]^2
(kp)^1/2   = [HCl]^2[O2]1/2/[Cl2][H2O]
KP         = (Kp)^1/2
(0.0753)^1/2 = [HCl]^2[O2]1/2/[Cl2][H2O]
0.274          = [HCl]^2[O2]1/2/[Cl2][H2O]
KP   = 0.274 >>>>answer
