What happens if you increase the concentration of a solution?
There are more collisions between reactants which lead to the products being formed more rapidly, because there are more molecules in a given space. Therefore the rate increases.

What do catalysts do?
They increase or decrease the rate of a reaction and the catalyst can be reused
2 of 3
Heat effects rates of reaction because...
The particles gain kinetic energy and collide with each other more often leading to a more successful collision.
