Investigating the effect that temperature has on the rate of reaction and therefore the amount of oxygen produced

Decomposition of atomic number 1 peroxide 2H2O O + 2H2O P lanning Aim:         Our aim is to investigate the effect that temperature has on the rate of response and the amount of oxygen that is produced. Prediction:         With reference book to my theory, I predict that the initial rate of re symboliseion allow for attach with the temperature rise up to 50°C where the enzyme utilize and released by the barm depart become denatured and drug abuse map normally, reducing the initial rate of reply greatly. This is explained by dint of the energizing theory, clashing theory and the lock and key hypothesis. possibleness and theory:         Catalase is an enzyme lay down in food such as potato. It is apply for removing enthalpy peroxide from cells. Catalase speeds up the chemical decomposition reaction of hydrogen peroxide into peeing and oxygen. It is able to speed up the decompos ition because of the shape of the hydrogen peroxide molecule. Enzymes are proteins that act as particle accelerators. They are do in cells. A catalyst is something, which speeds up a reaction but doesnt get used up in the reaction. wholeness can usually be used many times.         In this experiment the enzyme is the catalase in the yeast and the substrate is the hydrogen peroxide.

in that location are some(prenominal) theories, which has led me to predict that as the temperature increases, the place of reaction will increase. However, when the temperature gets above 50°C, I consider that the ra te of reaction will begin to decrease. One o! f the theories is the collision theory. Chemical reactions occur when particles of the reactant shake up with enough pushing (John Holman p225). If the temperature of the solution is high whence thither is to a greater extent chance of the particles colliding. This is because if the temperature increases the molecules have more energy so there is more collision. The more energy particles...
