| 62. | Investigate how the concentration of acid used affects the rate of a chemical reaction
Background: The speed of a reaction is known as a reaction rate. There are many factors that may affect the reaction rate, including:
Heat. When heat is introduced the atoms gain more kinetic energy and move at a faster rate and therefore collisions happen more often and more violently. ... Th...
