Equilibrium Question 609

Question: For the system $ A(g)+2B(g) $ ⇌ $ C(g) $ , the equilibrium concentrations are 0.06 mole/litre 0.12 mole/litre 0.216 mole/litre. The $ K_{eq} $ for the reaction is [CPMT 1983]

Options:

A) 250

B) 416

C) $ 4\times {10^{-3}} $

D) 125

Show Answer

Answer:

Correct Answer: A

Solution:

For reaction A + 2B ⇌ C $ K=\frac{[C]}{[A]{{[B]}^{2}}}=\frac{0.216}{0.06\times 0.12\times 0.12}=250 $ .
