The equilibrium constant K p for this reaction at 298 K, in terms of β equilibrium , is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Paragraph-1
X 2 (g) 
2 X (g)
Initial mole 1 0
t = t eq. (1– α ) 2 α
Given 2 α = β equilibrium
So α = 
Total mole at equilibrium = (1 + α ) = (1+ 
= 
= 
= 
P X(g) = 
= 
P Total
So K P = 
= 
K P = 
× P Total = 
So Ans. is = B
