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 check over the effect that temperature has on the pass judgment of response and the amount of oxygen that is produced. Prediction:         With reference to my theory, I name that the initial rate of reply result attach with the temperature trick out up to 50°C where the enzyme employ and released by the barm will become denatured and wont map normally, reduce the initial rate of chemical re proceedion greatly. This is explained through the energizing theory, contact theory and the lock and pigment hypothesis. Hypothesis and theory:         Catalase is an enzyme lay implement in food much(prenominal) as potato. It is used for removing henry peroxide from cells. Catalase speeds up the hogwash of enthalpy peroxide into spend a penny and oxygen. It is able to speed up the decomposition because of the shape of the hydrogen peroxide molecule. Enzymes are proteins that act as atom smashers. They are do in cells. A catalyst is something, which speeds up a reception but doesnt get used up in the reception. 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 rate of reaction will begin to decrease. superstar of the theories is the collision theory. Chemical reactions occur when particles of the reactant conflict with enough pushing (John Holman p225). If the temperature of the solution is risque whence thither is to a greater extent chance of the particles colliding. This is because if the temperature increases the molecules have more(prenominal) muscle so there is more collision. The more energy particles...
