Calculate the relative rate of diffusion of 1H2 (molar mass 2.0 g/mol) compared with 2H2 (molar mass 4.0 g/mol) and the relative rate of diffusion of O2 (molar mass 32 g/mol) compared with O3 (molar mass 48 g/mol).
5 problems on gas laws, please answer ALL problems, thank you!
1. Calculate the relative rate of diffusion of 1H2 (molar mass 2.0 g/mol) compared with 2H2 (molar mass 4.0 g/mol) and the relative rate of diffusion of O2 (molar mass 32 g/mol) compared with O3 (molar mass 48 g/mol).
2. Can the speed of a given molecule in a gas double at constant temperature? Explain your answer.
3. The distribution of molecular velocities in a sample of helium is shown in the picture attached below #5. If the sample is cooled, will the distribution of velocities look more like that of H2 or of H2O? Explain your answer.
4. A 1-L sample of CO initially at STP is heated to 546 K, and its volume is increased to 2 L.
