Problem

A sealed

2.00\,\text{L}

container is charged with

1.00\,\text{mol}

\text{N}_2\text{O}_4(g)

at a certain temperature. At equilibrium for the reaction

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

15.0\%

of the

\text{N}_2\text{O}_4

has dissociated. What is the value of

K_c

at this temperature? a)

7.06\times10^{-1}

3.53\times10^{-1}

5.3\times10^{-2}

2.6\times10^{-2}
