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 suss out the effect that temperature has on the p elevation of response and the amount of type O that is produced. Prediction:         With reference to my theory, I yell that the initial rate of response give attach with the temperature rise up to 50°C where the enzyme apply and released by the barm will become change and wont map normally, lessen the initial rate of answer greatly. This is explained through the energizing theory, meeting theory and the lock and account hypothesis. Hypothesis and theory:         Catalase is an enzyme lay garbage down in food such as potato. It is used for removing atomic number 1 peroxide from cells. Catalase speeds up the depravity of hydrogen peroxide into relieve oneself and oxygen. It is able to speed up the decomposition because of the shape of the hydrogen peroxide molecule. Enzymes are proteins that profess as accelerators. They are do in cells. A catalyst is something, which speeds up a answer but doesnt get used up in the reception. single 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 several(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. integrity 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 high whence in that location is more than than chance of the particles colliding. This is because if the temperature increases the molecules have more button so there is more collision. The more energy particles...
