Two containers of equal volumes contain the same gas at pressures \(P_1\) and \(P_2\) and absolute temperatures \(T_1\) and \(T_2\), respectively. On joining the vessels, the gas reaches a common pressure \(P\) and common temperature \(T\). The ratio \(\frac{P}{T}\) is equal to:

1. \(\frac{P_1}{T_1}+\frac{P_2}{T_2}\) 2. \(\frac{P_1T_1+P_2T_2}{(T_1+T_2)^2}\)
3. \(\frac{P_1T_2+P_2T_1}{(T_1+T_2)^2}\) 4. \(\frac{P_1}{2T_1}+\frac{P_2}{2T_2}\)

A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at \(300\) K. The ratio of the average rotational kinetic energy per O2 molecule to that per N2 molecule is:

1. 1 : 1
2. 1 : 2
3. 2 : 1
4. depends on the moments of inertia of the two molecules
