The value of Kp for the reaction,
2H2O(g)+2Cl2(g)⇌4HCl(g)+O2(g)2H_{2}O(g) + 2{Cl}_{2}(g) \rightleftharpoons 4HCl(g) + O_{2}(g) is
0.03 atm at 427º C, when the partial pressure are expressed in
atmosphere then the value of KC for the same reaction is

Show answer and solution
2H2O(g)+2Cl2(g)⇌4HCl(g)+O2(g)2H_{2}O(g) + 2{Cl}_{2}(g) \rightleftharpoons 4HCl(g) + O_{2}(g)
Kp = 0.03 T = 427oC = 700 K
Kp = KC(RT)1
KC=KPRT=[0.030.082×700]K_{C} = \frac{K_{P}}{RT} = \left\lbrack \frac{0.03}{0.082 \times 700} \right\rbrack
KC = 5.23 × 10-4
