Optional introduction of the analogy

Mum vs. baby

responsiveness, Gregor von Borstel, LNCU

Mum or baby throw without "resistance"

The basic concepts of reaction rates can be introduced without any knowlegde of chemical equilibrium.

Worksheet 1

Arbeitsmaterial Kinetik Bälle Schlacht

Reaction rate - what is this?

An analogy can be used for introduction

Worksheet 2

ChemZ, LNCU, rate of reaction, Gregor von Borstel

Measuring reaction rates

From nursery to laboratory

 

Experiment


 

Magnesium ribbon (ca. 2 cm) reacts with 3 ml Salzsäure (c = 1 mol/l)

Video time lapse

Worksheet 3

kinetics worksheet lncu Gregor von Borstel

Reaction rates - ΔV and Δc

From the change in gas volume to the change in concentration
