Problem

At 350\,K, the following equilibrium is established:

\text{N}_2\text{O}_4(g)\;\rightleftharpoons\;2\,\text{NO}_2(g)

The equilibrium partial pressures are

P_{\text{NO}_2}=0.80\,\text{atm}

and

P_{\text{N}_2\text{O}_4}=0.20\,\text{atm}

. What is the value of

K_p

at this temperature? (a)

1.8

(b)

3.2

(c)

0.31

(d)

4.0
