In this investigation I intend to explore the one of the factors that affects the rate of reactions. My research from textbooks and the Internet suggests that this depends on several factors; temperature, pressure, pH and concentration. After research and careful consideration, in my experiment I am going to investigate how a change in temperature could affect the rate of reaction. Using the enzyme in potatoes (peroxidase) reacting with hydrogen peroxide. Rate of reaction increases by: * An increase in temperature * An increase in concentration * An increase in surface area * A catalyst increases the rate but doesn't take part in the reaction The collision theory is when particles of substances collide with each other and there is a reaction. The higher the temperature the more energy the particles have for a faster reaction, more likely that the enzymes/substrates with collide an lock. An increase in temperature increases reactions rates because there is more...
