Which of the following graphs correctly represents Boyle's Law?

For the reaction ${\mathrm{SO}}_{2\left(\mathrm{g}\right)}+\frac{1}{2}{\mathrm{O}}_{2\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{SO}}_{3\left(\mathrm{g}\right)}$, the percentage yield of product at different pressures is shown in the figure. Then, which among the following is true?

Three flasks of equal volumes contain ${\mathrm{CH}}_4,{\mathrm{CO}}_2\&{\mathrm{Cl}}_2$ gases respectively. They will contain equal number of molecules if

Which among the following statements is/are incorrect regarding real gases?
(i) Their compressibility factor is never equal to unity $(Z\ne 1)$.
(ii) The deviations from ideal behavior are less at low pressures and high temperatures.
(iii) Intermolecular forces among gas molecules are equal to zero.
(iv) The obey Van der Waals equation, $\mathrm{PV}=\mathrm{nRT}$.

The density of an ideal gas can be given by where $P,V,M,T$ and $R$ respectively denote pressure, volume, molar-mass, temperature and universal gas constant.

Among the following, the maximum deviation from ideal gas behavior is expected from

Two flasks $\mathrm{A}$ and $\mathrm{B}$ have equal volumes. $\mathrm{A}$ is maintained at $300 \mathrm{K}$ and $\mathrm{B}$ at $600 \mathrm{K}$. Equal masses of ${\mathrm{H}}_2$ and ${\mathrm{CO}}_2$ are taken in flasks $\mathrm{A}$ and $\mathrm{B}$ respectively. Find the ratio of total $\mathrm{K}.\mathrm{E}$ of gases in flask $\mathrm{A}$ to that of $\mathrm{B}$.

When the temperature of a gas is increased from $30°\mathrm{C}$ to $930°\mathrm{C}$, the root mean square speed of the gas would
