1. How fast is the rate of effusion of N2 compared to that of Cl2?
2. Under the same conditions of temperature and pressure, (a) how many times faster will methane (CH4) effuse compared to Hydrochloric acid (HCl)? (b) If the Hydrochloric acid takes 25 sec to effuse, how long will the methane take?
3. A sample of gas occupies a volume of 200 mL at 25 atm. Calculate the new pressure if its volume is increased to 340 mL. (With a constant temperature)
