Q. In the gas phase reaction $C_2H_4 + H_2 \rightleftharpoons C_2H_6$, the equilibrium constant can be expressed in
AIIMS
AIIMS 1997
Equilibrium
A
$mole\, litre^{-1}$
25%
B
$mole\, litre^{-2}$
13%
C
$mole^{-1} litre^{-1}$
6%
D
$litre\, mole^{-1}$
56%
Solution:
Equilibrium constant
$\frac{\left[ C _{2} H _{6}\right]}{\left[ C _{2} H _{4}\right]\left[ H _{2}\right]}=\frac{\text { mole.litre }^{-1}}{\left(\text { mole.litre }^{.1}\right) \cdot\left(\text { mole.litre }^{-1}\right)}$
$=\frac{1}{\text { mole. litre }^{-1}}=\frac{\text { litre }}{\text { mole }}$
