Explain how increasing the concentration of a reactant will change the rate of the reaction
There are more particles per unit volume, so more frequent collisions and a faster rate of reaction

Explain how decreasing the temperature of a reaction changes the rate of a reaction
The particles will have less energy, so there are less successful collisions and a slower rate of reaction
