Identify the correct statements from the following I. For an ideal gas, the compressibility factor is 1.0 II. The kinetic energy of $\mathrm{NO}(g)$ (molar mass $=30 \mathrm{~g} \mathrm{~mol}^{-1}$ ) at $T(\mathrm{~K})$ is $x \mathrm{~J} \mathrm{~mol}^{-1}$. The kinetic energy of $\mathrm{N}_2 \mathrm{O}_4(g)\left(\right.$ molar mass $\left.=92 \mathrm{~g} \mathrm{~mol}^{-1}\right)$ at $T(\mathrm{~K})$ is $2 x \mathrm{~J} \mathrm{~mol}^{-1}$ III. The rate of diffusion of a gas is inversely proportional to square root of its density.
