Rate of Effusion Problems The average molecular speed in a sample of He gas at a certain temperature is 1.37x10 m/s. The average molecular speed in a sample of Kr gas is m/s at the same temperature. The rate of effusion of CH4 gas through a porous barrier is observed to be 3.73 x 10-4 mol/h. Under the same conditions, the rate of effusion of N2 gas would be mol/h.
