1
Q
Temperature
A
the higher the temperature, the greater the rate of reaction.
2
Q
Concentration
A
Thus, increasing the concentration of the reactants usually results in a higher reaction rate.
3
Q
Surface area
A
many small particles have a greater total surface area than one large particle. The more surface contact between reactants, the higher the rate of reaction.
4
Q
Catalyst
A
When catalysts are used, a reaction can proceed although less energy is added during the reaction.
