In theory, what will be the ratio of the rate of effusion of potassium to the rate of effusion of germanium?
Rate of effusion is inversely proportional to square root of molar mass
rate = k*sqrt(1/M)
M is molar mass
If we take ratio, above expression becomes
rate(K)/rate(Ge) = sqrt (M(Ge)/M(K))
we have:
M(K) = 39.1 g/mol
M(Ge) = 72.63 g/mol
rate(K)/rate(Ge) = sqrt (72.63/39.1)
rate(K)/rate(Ge) = sqrt (1.8575)
rate(K)/rate(Ge) = 1.3629
Answer: 1.36

1. Calculate the ratio of effusion rates of O2 and H2. What is given? What do you want to know? What else do you need to know? Solve the problem:
Calculate the ratio of the effusion rate of oxygen (O2) to that of carbon dioxide gas (CO2). Express your answer in decimal form and calculate your answer to at least four sig figs. 4.690 Graham's Law of Effusion is: rate/ratez - (M/M)2 where M - molar mass A cylinder with a moveable piston contains 92g of Nitrogen. The external pressure is constant at 1.00 atm. The initial temperature is 200K. When the temperature is decreased by 70 K, by putting...
9. Diffusion and Effusion. What distinguishes effusion from diffusion? Effusion is the diffusion of very heavy molecules or other partides. During effusion, molecules spread out until their concentration is uniform. During effusion, a gas escapes through a tiny hole in its container. Effusion is the diffusion of very light molecules or other particles

Please explain and show steps. Thanks! The rate of effusion of a particular gas was measured to be 28.6 mL/min. Under the same conditions, the rate of effusion of pure methane (CH4) gas is 48.4 mL/min. What is the molar mass of the unknown gas? g/mol
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.
The rate of effusion of NH3 gas through a porous barrier is observed to be 3.47 x 10 mol/h. Under the same conditions, the rate of effusion of O2 gas would be mol/h.
