Effusion lab
The distribtion curve shown above can be labelled as,
The first box on the leftmost region of curved depicts = slower particles
The maxima on the curve depicts the = most probable speed
The second lower point to the right of most probable speed depicts = average speed
The last box on the right depicts = faster particles
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.

A) Label the graph to show the effects of an increase in non-labor income Label all relevant parts of the graph. (You might or might not use every line/curve 0ท the graph.) B) Label the graph to show the effects of an increase in the wage rate. Label all relevant parts of the graph. (You might or might not use every line/curve on the graph)
The following graph shows the distribution of molecular. velocities for two different molecules (A and B) at the same temperature.Part AWhich molecule has the higher molar mass? Which molecule would have the higher rate of effusion?
B) Label the graph to show the effects of an increase in the wage rate. Label all relevant parts of the graph. (You might or might not use every line/curve on the graph.)
label correctly (studying for lab practical)
