The molar masses of four unknown gases are shown in the table. Molar Mass of Unknown GasesGas Molar Mass
A 44 g/mol
B 20 g/mol
C 30 g/mol
D 32 g/mol
Which gas is likely to have the highest rate of effusion?

Respuesta :

Answer:

Gas B

Explanation:

diffusion/effusion increases when:

- Temperature increases

- A gas has lower molar mass

- Particles are moving quickly

diffusion/effusion decreases when:

- Temperature decreases

- A gas has higher molar mass

- Particles are moving slowly

Hence: since gas B has the lowest molar mass, it has the highest rate of effusion

I also took the test so I know it is right
