What is a catalyst?
A substance that speeds up chemical reactions
What does a catalyst offer?
An alternative pathway at a lower activation energy
What happens when the number of reactant particles doubles?
The more frequent collisions between the particles means there is an increase in the rate of reaction.
How does temperature effect the rate of reaction?
The particles gain more kinetic energy meaning more successful collision happen leading to an increase in the rate of reaction.
What do large pieces of solid have?
A small surface area to volume ratio
What happens when the solid is broken up?
This will increase the surface area to volume ratio
What is a reversible reaction?
When the reactants form a product. The products then react together to reform the reactants.
