Chemistry - Chemical Equilibrium Question with Solution | TestHub

In a rigid container ${\mathrm{NH}}_3$ is kept at certain temperature where its pressure is found to be ${\mathrm{P}}_1$. If on doubling the temperature, it is completely dissociated into ${\mathrm{N}}_2$ and ${\mathrm{H}}_2$. At these conditions, pressure of mixture is found to be ${\mathrm{P}}_2$. Find ratio of ${\mathrm{P}}_2$ to ${\mathrm{P}}_1$
