Q
Q: Which of the following gases will have the highest average speed at the same temperature?
Solution:
Hydrogen (H2) has the lowest molar mass, thus it will have the highest average speed according to the kinetic theory.
Steps: 5
Show Steps
Step 1: Understand that gases move at different speeds depending on their mass.
Step 2: Know that lighter gases move faster than heavier gases at the same temperature.
Step 3: Identify the molar mass of the gases in question. For example, hydrogen (H2) has a low molar mass.
Step 4: Compare the molar masses of the gases. The gas with the lowest molar mass will have the highest average speed.
Step 5: Conclude that hydrogen (H2) has the lowest molar mass among common gases, so it will have the highest average speed.
