(a) Place the following gases in order of increasing average molecular speed at 300 K: CO. SF6, H2S. C12. HBr. (b) Calculate the rms speeds of CO and C12 molecules at 300 K. (c) Calculate the most probable speeds of CO and C12 molecules at 300 K.
ANSWER:
Step 1 of 4
The expression for root mean square speed is as follows;
.....................(1)
Here,
= The molar mass of particle
