For a reaction, N_2 O_5( g ) → 2 NO_2( g ) +1/2 O_2( g ) in a constant volume container, no products were present initially. The final pressure of…
For a reaction, $\displaystyle \mathrm{N}_2 \mathrm{O}_{5(\mathrm{~g})} \rightarrow 2 \mathrm{NO}_{2(\mathrm{~g})}+\frac{1}{2} \mathrm{O}_{2(\mathrm{~g})}$ in a constant volume container, no products were present initially. The final pressure of the system when $\displaystyle 50 \%$ of reaction gets completed is
