37.8 \mathrm{~g} \mathrm{~N}_2 \mathrm{O}_5

was taken in a 1 L reaction vessel and allowed to undergo the following reaction at 500 K

2 \mathrm{~N}_2 \mathrm{O}_{5(\mathrm{~g})} \rightleftharpoons 2 \mathrm{~N}_2 \mathrm{O}_{4(\mathrm{~g})}+\mathrm{O}_{2(\mathrm{~g})}

The total pressure at equilibrium was found to be 18.65 bar. Then,

\mathrm{Kp}=
