I just tried this and got the correct answer... Using the hint, i.e. 1/2a^2, I made a=M/2RT, and included the terms (square root 2/pi times (M/RT)^3) After plugging the a value in, I did all the algebra to get to (8RT/piM)^.5.

Sure. Since the integral was equal to 1/2a^2, it appeared the a value would be equal to M/RT, getting that from the exponent of e. Putting that value in for a however does not yield the answer I want. I then tried to see if integrating that integral in the hint would help me understand, I...

Ok I am stuck. I tried to integrate the distribution constant but got stuck, and also wondered why I need to do it if in the hint on the problem they gave it to me. Although in the hint I am not sure where "x" went, because when I integrate the constant the "x" term should still be there. Any...

Ok, I will attempt to integrate the constant you gave then, although I am not sure I know how to do it. I will work with it and post again and see if you can give some guiding help. Thanks.

The f(s) delta s. Is the fraction of molecules between two speeds. The delta s is just the change in speed you have, I.e. if you want the fraction between 300 and 310 m/s, you do the normalization constant with 300 and then multiply it by 10 for the fraction

The mean speed is the sum off all the speeds of all the molecules divided by the number of molecules. I also know that the mean speed is related to the rms speed of the molecules by the equation mean speed= (8/3pi)^.5 times the rms speed. Also I have been plugging in numbers and found the...

Homework Statement Confirm that the mean speed of molecules of molar mass M at a temperature T is equal to (8RT/piM)^1/2. Hint: You will need an integral of the form ∫ (where a=0, and b=infinity) x^3*e^(-ax^2) dx = 1/2a^2. Homework Equations The Maxwell speed distribution formula we...
