Changing Equilibrium Systems: Increasing the Concentration of a Reactant

Chemical Equilibrium

What happens when you add more reactant to an equilibrium? This video demonstrates how an increase in reactants affects reaction rates in accordance with Le Chatelier’s principle. Students will observe how the colour of a solution of ferric thiocyanate changes when reactants are added. Footage of a real lab demonstration makes this essential viewing for senior secondary chemistry students.
