K(c) for the reaction N(2)O(g)hArr2NO(2)...

`K_(c)` for the reaction `N_(2)O(g)hArr2NO_(2)(g)` is `4.63xx10^(-3)` at `25^(2)C`.
a. What is the value of `K_(p)` at this temperature?
b. At `25^(@)C`, if the partial pressure of `N_(2)O_(4)(g)` at equilibrium is 0.2 atm, calculate equilibrium pressure of `NO_(2)(g)`

Text Solution

Verified by Experts

`k_(p) = (P_(NO_(2)^(2)))/(P_(N_(2)O_(4))) `
` 0.1132 = (P_(NO_(2)^(2)))/(0.2) `
`P_(NO_(2)^(2)) = 0.2264`
`P_(NO_(2) ) = 0.15 ` atm
