The average translational energy and the rms speed of molecules in a sample of oxygen gas at 300 K are \(6.21 \times 10^{-21} \downarrow\) and 484 m/s, respectively. The corresponding values at 600 K are nearly (assuming ideal gas behavior)
- \(12.42 \times 10^{-21} \downharpoonleft 968 \mathrm{~m} / \mathrm{s}\)
- \(8.78 \times 10^{-21} \downharpoonleft 684 \mathrm{~m} / \mathrm{s}\)
- \(6.21 \times 10^{-21} \downharpoonleft 968 \mathrm{~m} / \mathrm{s}\)
- \(12.42 \times 10^{-21} \downharpoonleft 684 \mathrm{~m} / \mathrm{s}\)
Answer
(D) 12.42 10^ -21 684 ~m / s
