Chemical, environmental, and nuclear engineers must be able to predict the changes in chemical concen- tration in a reaction. A model used for many single reactant process is

Rate of change of concentration = −kC n

where C is the chemical concentration and k is the rate constant. The order of the reaction is the value of the exponent n. It is known that the solution for a first-order reaction (n = 1) is

C (t) = C (0)e−kt

and the solution for a second order reaction (n = 2) is

1 1

C (t) = C (0) + kt.

The data in Table 1 describes the gas-phase decomposition of nitrogen at 300? :

2N O2 −→ 2N O + O2.

Use the data given in Table 1 to determine whether this is a first-order or second-order reaction, and estimate the value of the constant k.

I need a matlab file for this.. Thank you so much!
