1.	Assertion (A): Rate of diffusion of H_2 gas is the highest. Reason (R) : Rate of diffusion of a gas is inversely proportional to molecular weight of the gas.
Answer» A & R are true, R explains A A & R are true, R does not explain A A is true R is false A is false R is true SOLUTION :`H_2` is highest gas and `r alpha 1/(sqrtM)`.
