Question

Assertion: A lighter gas diffuses more rapidly than heavier gas.
Reason: At a given temperature, the rate of diffusion of a gas is inversely proportional to the square root of its density.
A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).
B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).
C. If (`A`) is correct, but (`R`) is incorrect.
D. If (`A`) is incorrect, but (`R`) is correct.

Answer 1

Correct Answer - A::B::C::D
Rate of diffusion `prop sqrt((1)/(Molecular mass))`
