Question

How many times faster does helium gas effuse when compared to chlorine gas? (Helium gas is monoatomic; Chlorine Gas is diatomic) * 1 point 1.2 times faster 4.2 times faster 3.1 times faster 2.5 times faster

Answer 1

Answer:

4.2 times faster

Explanation:

From Graham's law of diffusion

R1/R2 = (M2/M1)^1/2

Let R1= rate for He

R2= rate for Cl2

R1=R2×(M2/M1)^1/2

R1= R2(71/4)^1/2= R2× 4.2
