Questions & Step-by-Step Solutions
Which of the following gases would have the highest rate of diffusion at a given temperature?
Correct Answer: Hydrogen (H2)
Step 1: Understand what diffusion means. Diffusion is the process where gas molecules spread out from an area of high concentration to an area of low concentration.
Step 2: Know that the rate of diffusion depends on the molar mass of the gas. Lighter gases diffuse faster than heavier gases.
Step 3: Identify the gases you are comparing. In this case, we are looking at hydrogen (H2) and possibly other gases.
Step 4: Find the molar mass of hydrogen (H2). Hydrogen has a molar mass of about 2 grams per mole, which is very low.
Step 5: Compare the molar mass of hydrogen with other gases. The lower the molar mass, the faster the diffusion rate.
Step 6: Conclude that since hydrogen has the lowest molar mass among the gases, it will have the highest rate of diffusion at a given temperature.
