Which of the following equations could be possibly used to determine the rate of diffusion of a gas in an enclosed flask once the valve is opened?

Correct Answer: B. KE = (1/2)mv2
The rate of expansion (or diffusion) is directly proportional to the mean velocity of the gas molecules. The only equation that has a term for velocity is the one in choice B.
