Le Chatelier’s Principle | GCSE Chemistry Practice
If a change is made to a system at equilibrium, the system shifts to counteract the change.
If you increase the concentration of a reactant, which way does the equilibrium shift?
What is Le Chatelier’s Principle | Practice?
"A principle used to predict the effect of a change in conditions on a chemical system in dynamic equilibrium."
Increasing the concentration of reactants increases the rate because particles...
Why does a powder react faster than a single large lump of the same mass?
How does a catalyst increase the rate of reaction?
Equilibrium Shifts
Dynamic Equilibrium: Rates of forward and reverse reactions are equal.
Increase Concentration: Shift towards products.
Increase Temperature: Shift towards the endothermic direction.
Increase Pressure: Shift towards the side with fewer gas molecules.
Advanced Tip: A catalyst DOES NOT change the position of equilibrium; it only helps reach it faster!

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
