The temperature in the stratosphere is 223C. Calculate the root-mean-square speeds of N2, O2, and O3 molecules
Question:
Check: Since the molar masses of the gases increase in the order: N2 < O2 < O3, we expect the lightest gas (N2) to move the fastest on average and the heaviest gas (O3) to move the slowest on average. This is confirmed in the above calculation.
