2. The following reaction occurs inside a container that has a volume of 4 litres: 2NH 3(g) - N 2(g) + 3H 2(g) a. Write the rate expression for this reaction. b. A chemist finds that there is 0.006 mols of hydrogen gas in the container after a period of time. What is the concentration of hydrogen gas? c. The chemist knows that the initial concentration of H 2 was 0 mol/L, and that it took 15 seconds to reach the concentration in part b. What is the average reaction rate over this time? d. How many mols of ammonia (NH 3) have been used up in this time period? e. What mass of ammonia is this?
