Establishing order of chemical reaction using mathematical modelling

The paper presents how we can apply mathematics in teaching of chemistry and chemical kinetics in the classroom. We describe here how chemical reaction order depends on the concentration of the reactants, using differential and integral calculus. Subsequently, we look into solving the problem of determining the order of chemical reaction and the problem is solved by mathematical models, using properties of linear functions. We have used a software package GeoGebra, especially the use of tables, forming a list of points, their graphical representation, fitting curves for modelling of our examples.
