Chemistry - Chemical Equilibrium Question with Solution | TestHub

$37.8\mathrm{g}{\mathrm{N}}_2{\mathrm{O}}_5$ 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, $\mathrm{Kp}=$ ______ $\times 10^{-2}$ [nearest integer] Assume ${\mathrm{N}}_2{\mathrm{O}}_5$ to behave ideally under these conditions. Given: $\mathrm{R}=0.082$ bar $\mathrm{L}{\mathrm{mol}}^{-1}{\mathrm{K}}^{-1}$
