Chemistry - Ideal Gas Question with Solution | TestHub

Since temperature, pressure and volume are same for both the gases implies that their number of moles, on mixing becomes double. Keeping the temperature same and reducing the volume to half, pressure becomes 4 times.
${\mathrm{P}}_1{\mathrm{V}}_1={\mathrm{n}}_1\mathrm{R}\mathrm{T}$
${\mathrm{P}}_2.\frac{{\mathrm{V}}_1}{2}=2\mathrm{n},\mathrm{R}\mathrm{T}$
That is${\mathrm{P}}_2=4{\mathrm{P}}_1$
