1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...

I need help with the rate constants for trials 1 through 4. I
put as much info as I thought would be necessary. The last question
I posted I was told I didn't have enough info, so I hope this is
enough.
This is all the info I was given to solve the questions, so this
has to be enough to solve them.
