Question

The equilibrium constant, $K_{p},$ is 0.14 at $25^{\circ} \mathrm{C}$ for the following reaction: $$ \mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{g}) \rightleftharpoons 2 \mathrm{NO}_{2}(\mathrm{g}) $$ If the total pressure of the gas mixture is 2.5 atm at equilibrium, what is the partial pressure of each gas?

Step 1

We are given that $K_{p} = 0.14$ at $25^{\circ} \mathrm{C}$, so we can use this to set up an equation relating the partial pressures: $$ 0.14 = \frac{P_{\mathrm{NO}_{2}}^{2}}{P_{\mathrm{N}_{2}\mathrm{O}_{4}}} $$ Show more…
