What happens when you increase the pressure on an equilibrium? This video demonstrates how changing pressure affects reaction rates in accordance with Le Chatelier’s principle. Students will observe the colour of a gaseous mixture of nitrogen dioxide and dinitrogen tetroxide under different pressure conditions. Footage of a real lab demonstration makes this essential viewing for senior secondary chemistry students.
