Abstract

What to look out for graphically when teaching reaction kinetics. Chemists often represent the underlying models of chemical kinetics graphically, such as when plotting concentration v time or rate v time. Studies have shown that students have difficulties understanding rate and rate constant, and that graphical representations often make it more challenging. A recent study from researchers in the US investigated the relationship between students' models of reaction rate, and the graphical representations they use to describe them.
