In the gaseous phase reaction C(2)H(4)...

In the gaseous phase reaction
`C_(2)H_(4) +H_(2) hArr C_(2)H_(6),` the equilibrium constant can be expressed in the units to :

A

`"litre"^(-1)"mole"^(-1)`

B

`"litremole"^(-1)`

C

`"mole"^(2)"litre"^(-2)`

D

`"mole litre"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K=([C_2H_6])/([C_2H_4][H_2])=(["mole"//"litre"])/(["mole"//"litre"]["mole"//"litre"])`
= litre/mole. or litre `"mole"^(-1)`
