Equilibrium constants (K) for the reacti...

Equilibrium constants `(K)` for the reaction `2NO(g)+Cl_(2)(g)hArr2NOCl(g)` is correctly given by the expression

A

`([NOCl]^(2))/([NO]^(2)[Cl_(2)])`

B

`([2NOCl])/([2NO][Cl_(2)])`

C

`([NO]^(2)+[Cl_(2)])/([NOCl])`

D

`([NO]^(2)[Cl_(2)])/([NOCl]^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`2NO(g)+Cl_(2)(g)overset(K)(hArr)2NOCl(g)`
According the law of mass action
`K=([NOCl]^(2))/([NO]^(2)[Cl_(2)])`
