In this question, we don't have to apply Grahm's law cuz it is far simple

What they said, rNH3=1.6(rCO₂) ,the questions word in equation

Now we can also write it as

rNH₃/rCO₂ = 1.6/1

But wait isn't option C is same just reprocalliting on both sides?

Two options right, what to do now?

Select in Alphabetic order, so we will select option B

Dont say, you don't know,

rNH₃ means rate of diffusion of NH₃

rCO₂ means the rate of diffusion of CO₂

This option says rCO₂ is 1.6 times faster than rNH₃ because if we cross multiply we get 1.6(rNH₃) =rCO₂

Right option as proved.

Also right but will prefer B

Options have the right answer.
