Questions & Step-by-Step Solutions
Which of the following gases will have the highest rate of diffusion at a given temperature?
Step 1: Understand that diffusion is the process where gas molecules spread out from an area of high concentration to an area of low concentration.
Step 2: Learn about Graham's law of effusion, which states that lighter gases diffuse faster than heavier gases.
Step 3: Identify the gases in the question and find their molar masses (the weight of one mole of the gas).
Step 4: Compare the molar masses of the gases. The gas with the lowest molar mass will diffuse the fastest.
Step 5: Conclude that H2 (hydrogen gas) has the lowest molar mass among common gases, so it will have the highest rate of diffusion at a given temperature.
