Problem

At 298 K the dimerization of nitrogen dioxide is represented by

2\mathrm{NO_2(g)}\rightleftharpoons\mathrm{N_2O_4(g)}

with

K_p=0.15

. A 2.0 L rigid container is filled with 0.40 mol of

\mathrm{NO_2}

and no

\mathrm{N_2O_4}

. Which species will have the greater number of moles at equilibrium? a) The two species will be present in approximately equal amounts b)

\mathrm{N_2O_4}

\mathrm{NO_2}

d) The information is insufficient to predict which species predominates
