In zero reaction, the decomposition of ammonia gas on a tungsten surface has a rate of 22.3 x10-4 moles liter-1 minute-1 at 1100 K when the concentration of the NH3 = 0.01M
a. Why doubling the concentration of the ammonia has no effect on the rate of the reaction. Why this happens.
c. What is the concentration of the ammonia after 30 minutes have elapsed?
d. How long will it take for the concentration of the ammonia to drop to a concentration of 0.001 M?
e. If this reaction was second order, and the rate and initial concentration remained the same, calculate the value for the specific rate constant
