$\huge{ \boxed{ \red{ \mathcal{☆Reaction\: Rate:}}}}$

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

There are four factors that affect the rate (speed) of a chemical reaction:

• temperature
• concentration
• particle size
• use of a catalyst
