If concentration is expressed as mol L^(...

If concentration is expressed as mol `L^(-)`, the equilibrium constant, K for the reaction :
`2N_(2)O_(5)(g)hArr 4NO_(2)(g)+O_(2)(g)`
has the units :

A

`mol^(3)L^(-3)`

B

`mol L^(-1)`

C

`mol^(3)L^(-1)`

D

no units.

Text Solution

Verified by Experts

The correct Answer is:
A
`K=([NO_(2)]^(4)[O_(2)])/([N_(2)O_(5)]^(2))=((mol//L)^(4)(mol//L))/((mol//L)^(2))`
`= mol^(3)L^(-3)`
