Question 1. Derive the expression for the root-mean-square speed based on the Maxwell speed distribution.
Question 2. At what pressure does the mean free path of Argon 45 degree celcsius become similar to the diameter of a circular vessel of a volume 1.0 dm^3 that contains it?
what is the reaction order? If the unit is M^-1 s^-1, what is the reaction order? Use the rate laws to determine the unit for the rate constant.
If a 1.84 g sample of an alkaline Earth metal hydride was treated with an excess of dilute hydrochloric acid as well as the resulting gas was collected in a 1.000 L container at 20 C. The measured pressure of the gas was 750.0 mmHg.
