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 informant to my theory, I predict that the initial rate of re movemention go out attach with the temperature rise up to 50°C where the enzyme employ and released by the barm entrust become denatured and habit map normally, reducing the initial rate of reply greatly. This is explained through with(predicate) the energizing theory, clashing theory and the lock and key hypothesis. shot and theory:         Catalase is an enzyme lay down in food such(prenominal) as potato. It is utilize for removing enthalpy peroxide from cells. Catalase speeds up the depravity of hydrogen peroxide into peeing and oxygen. It is able to speed up the decomposition because of t he shape of the hydrogen peroxide molecule. Enzymes are proteins that act as catalysts. 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 rate of reaction will begin to d ecrease. One of the theories is the collisio! n theory. Chemical reactions occur when particles of the reactant clash with enough pushing (John Holman p225). If the temperature of the solution is high whence on that point is more(prenominal) 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...
