Q: Which gas has the highest rate of diffusion at a given temperature?
Solution: Helium (He) has the highest rate of diffusion due to its low molar mass.
Steps: 5
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 mass of the gas molecules. Lighter molecules diffuse faster than heavier ones.
Step 3: Identify the gas in question. In this case, we are looking at helium (He).
Step 4: Check the molar mass of helium. Helium has a very low molar mass compared to other gases.
Step 5: Conclude that because helium has the lowest molar mass, it will diffuse faster than other gases at the same temperature.
