Reaction rate
The change in concentration of reactants or products per unit time
What is the collision theory
The collision theory is a model that explains reaction rate as the result of particles colliding with a certain minimum energy to form products
What are catalysts and how do they work
Catalysts are substances that increase the rate of a chemical reaction without undergoing a permanent change itself. A catalyst increases the rate of a reaction by providing an alternative path of the lower activation energy therefore decreasing the net activation energy
Explain what is meant by open and closed systems
An open system continuously interacts with its environment whilst a closed system is isolated from its surroundings
What is a reversible reaction
A reaction is reversible when products can be converted back to reactants and vice versa
Explain what is meant by chemical equilibrium
It is a dynamic equilibrium when the rate of the forward reaction equals the rate of the reverse reaction
State le chatelier's principle
When the equilibrium in a closed system is disturbed the system will reinstate a new equilibrium by favouring the reaction that will oppose the disturbance
