Chemistry - Ideal Gas Question with Solution | TestHub

For a reaction, ${\mathrm{N}}_2{\mathrm{O}}_{5(\mathrm{g})}\to 2{\mathrm{NO}}_{2(\mathrm{g})}+\frac{1}{2}{\mathrm{O}}_{2(\mathrm{g})}$ in a constant volume container, no products were present initially. The final pressure of the system when $50\%$ of reaction gets completed is
