For the reaction `N_(2)O_(4)hArr2NO_(2)`, the concentrations of an equilibrium mixture at 293 K are: `[N_(2)O_(4)]=4.50xx10^(-2)` mol `L^(-1)` and `[NO_(2)]=1.61xx10^(-2)` mol `L^(-1)`. What is the value of equilibrium constant?

Text Solution

Verified by Experts

The correct Answer is:
`5.76xx10^(-3)`
`K_(c)=([NO_(2)]^(2))/([N_(2)O_(4)])`
