Using experimental results to determine the order of a chemical reaction and the rate constant from your understanding of chemical kinetics and species half life.

A reaction is defined by the following scheme:

X à  Y

When the concentration of X in a solution is 1.02 M, the half-life (t1/2) is 160 seconds.

When the concentration of X in solution is 2.05 M, the half-life (t1/2) is 80 seconds.

The above information applies when the reaction takes place at 25 degrees Celsius.

(a) What is the order of the reaction?
(b) Calculate the rate constant for the reaction.
