In a study of ammonia production, an industrial chemist discovers that the compound decomposes to its elements N2 and H2 in a first order process. She collects the following data:
Time (s) 0 1.000 2.000
[NH3] (mol/L) 4.000 3.986 3.974
a) Use graphical methods to determine the rate constant.
b) What is the half-life for ammonia decomposition?
