Integrated Rate Law

#### Q. The decomposition of ammonia gas on a tungsten surface is zero order reaction with a rate of 2.5 x 10 -4 moles liter-1 minute-1 at 1100 K when the concentration of the NH3 = 0.040M a. Write the rate expression for the reaction and determine the value of the specific rate constant (be sure to include the correct units) b. What is the concentration of the ammonia after 20 minutes have elapsed? c. How long will it take for the concentration of the ammonia to drop to a concentration of 0.001 M?
