1) The most probable speed formula behaves similarly to the molecular speed formula. Calculate the most probable speeds of the CO and Cl2 molecules by providing line-by-line solutions for each molecule. You must show your work for each gas to get full credit. Compare the molecular speeds of the CO and Cl2 molecules at 300 K by explaining any potential fundamental differences between the molecules. Finally, from your calculations what is the trend in similarities between rms speeds for CO and Cl2 and the most probable speeds for CO and Cl2?

sinnce the temperature is the same for all gases, the average kinetic energy is the same as well.

KE = 1/2 mv^2 so the lower the molar mass of the gas, the greater the average molecular velocity (speed).

CO= 28 g/mol

SF6=146

H2S=34

Cl2=71

HBr= 81 g/mol

CO>H2S>Cl2>HBr>SF6

2)Rms of CO / Rms of Cl2= sqrt(Cl2/CO)=sqrt(71/28)=1.59

3)=sqrt(71/28)1.59
