Question

Which of the following leads to a higher rate of effusion?

Answers:
1. Reduced temperature
2. Lower molar mass
3. Slower particle movement
4. Cooler gas sample

Answer 1

2. Lower Molar Mass

Step-by-step explanation:

effusion can increase with either temperature increase, faster moving particles, or when the gas has lower molar mass. the only answer option that fits the description is answer option 2. Lower molar mass

Answer 2

Lower molar mass :)
