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

Given,
`Na_(2)O_(4)(g) hArr 2NO_(2)(g)`
`k_(C) = 4.63 xx 10^(-3)`
`k_(p) = k_(C)(RT) Delta n`
` = 4.63 xx 10^(-3) xx 0.0821 xx 298 [Delta n = 1]`
` = 113.27 xx 10^(-3)`
` = 0.1132`
