Equilibrium Question 620
Question: In the gas phase reaction, $ C_2H_4+H_2 $ ⇌ $ C_2H_6 $ , the equilibrium constant can be expressed in units of [CBSE PMT 1992; Pb. PMT 1999]
Options:
A) $ litr{e^{-1}},mol{e^{-1}} $
B) $ litre,mol{e^{-1}} $
C) $ mole^{2},litr{e^{-2}} $
D) $ mole,litr{e^{-1}} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ K=\frac{[C_2H_6]}{[C_2H_4][H_2]}=\frac{[mole/litre]}{[mole/litre][mole/litre]} $ = litre/mole. or litre mole-1.
