The equilibrium constant at 298 K for a reaction A + B 
C + D is 100. If the initial concentration of all the four species were 1 M each, then equilibrium concentration of D (in mol L –1 ) will be :
Text Solution
Verified by ExpertsThe correct answer is:
B
A + B 
C + D
t = 0 1 1 1 1
t eq 1–x 1–x 1 + x 1 + x
⇒ 
= 100 ⇒ 
= 10
⇒ 1 + x = 10 – 10x ⇒ 11x = 9
⇒ x = 
⇒ [D] = 1 + 
⇒ [D] = 1.818
