Question

Rate of effusion of a gas is volume of gas escaping per second.

If the statement is true, enter 1 if false enter 0.

Answer 1

Effusion refers to the movement of gas molecules from an enclosed space into a evacuated space. The rate at which a gas of molar mass M effuses which is typically expressed as the number of molecules passing through the hole per second is:

$Rate=\frac{pA{N}_A}{\sqrt{2\pi MRT}}$
