The formula for methane is $\text{CH}_4$ and the formula for ethane is $\text{C}_2\text{H}_6$. Which row gives the definition of diffusion and compares the relative rates of diffusion for methane and ethane?
- Aparticles move from a high concentration to a low concentration; ethane diffuses more quickly than methane
- Bparticles move from a high concentration to a low concentration; methane diffuses more quickly than ethane
- Cparticles move from a low concentration to a high concentration; ethane diffuses more quickly than methane
- Dparticles move from a low concentration to a high concentration; methane diffuses more quickly than ethane
