Rates of reaction

This collection of classroom resources features activities from our Rates of reaction course for teachers, from our Teaching Chemistry series. This collection is most valuable to those who have attended this course and wish to put into practice with their students some of the ideas and activities presented as part of that event. Please note that this list is not exhaustive; not all trainer activities have a corresponding classroom resource. In some circumstances there is variation between the training resource and classroom resource.


Starters-3by2

Kinetics starters 1 (16–18)

Use this Starter for ten to help embed kinetics theories including collision theory and the Maxwell-Boltzmann distribution.

AfL: What is a chemical reaction?

Assessment for Learning is an effective way of actively involving students in their learning. Each session plan comes with suggestions about how to organise activities and worksheets that may be used with students.

The effect of temperature on reaction rate

Investigate the effect of temperature on the rate of reaction between sodium thiosulfate and hydrochloric acid to better understand basic collision theory

Image

The effect of concentration on reaction rate

Sodium thiosulfate solution is reacted with acid – a sulfur precipitate forms. The time taken for a certain amount of sulfur to form can be used to indicate the rate of the reaction.

Observing chemical changes

Experiment with microscale displacement, redox and precipitation reactions between various salts including potassium managanate, barium nitrate and ammonium vanadate. Observe and identify the chemical changes that take place in this visually engaging practical

A burning splint

Burning milk powder

Produce a spectacular fireball by sprinkling milk powder over a flame and witness how an increased surface area can also increase reaction rates.

Image

A visible activated complex

A simple demonstration of catalysis also introducing the idea of an activated complex and to allow discussion of the mechanism of catalysis.

FEATURE-catalyst-300

The evolution of catalytic converters

From early smog problems to modern concerns about air pollution, catalysts pave the way in controlling the emissions from combustion engines

Chemistry in your cupboard

In association with

Link the post-16 topics of acid and base neutralisation, weak acids, bonding and carboxylic acids to the topic of antacids. Learn about a range of real life contexts for these chemical ideas through written material, and questions to encourage learning and test understanding.

Iodine clock demonstration video

In association with

A video and teacher notes providing an introduction to reaction rates and kinetics, in which a colourless solution changes to dark blue.
