At a certain temperature 2 moles of carbonmonoxide and 3 moles of chlorine were allowed to reach equilibrium according to the reaction
`CO+Cl_(2)hArrCOCl_(2)` in a 5 lit vessel. At equilibrium if one mole of CO is present then equilibrium constant for the reaction is :

A

2

B

2.5

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
`CO+Cl_(2)hArrCOCl_(2)`
At t=0 2 3 0
At equilibrium (2-1) (3-1) 1
Concentrations `1/5` `2/5` `1/5`
`K_(C)=([CoCl_(2)])/([Co][Cl_(2)])=(1//5)/(1/5xx2/5)=25/10` or `K_(c)=2.5`
