Edexcel IGCSE Chemistry 3 21c Catalysts and Equilibrium Position Questions

Practise catalyst-equilibrium questions by separating faster reaction rate from unchanged equilibrium yield in reversible reactions.

Exam points

Predict that a catalyst does not change the equilibrium yield in a reversible reaction.
Explain that a catalyst speeds up the forward and reverse reactions equally.

[Maximum number: 2]

Gaseous ethanol is manufactured by reacting ethene gas with steam.

This is the equation for the reaction.
