How Does Concentration Affect the Rate of Reaction? By Danielle Clarke Introduction This investigation is about finding out how concentration affects the rate of reaction in an experiment. Th rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. I already know that by changing the variables you can alter the rate of reaction by increase or decrease. The variables are: Temperature: In terms of particles, if you increase the temperature of a chemical reaction the particles gain kinetic energy and heating then makes them move faster. When particles move faster they collide more often and with more energy, resulting in more successful collisions. A decrease in temperature would have the opposite effect. Concentration: An increase in the concentration of a chemical substance reacting with another would result in the particles crowding closer together due to more particles being added. This process makes it...
