Aim: To investigate the action of the enzyme catalyse Hydrogen Peroxide Water + Oxygen 2 H2 02 2H2 0 + 02 Hydrogen peroxide is a poisonous waste product in chemical reactions. Catalyse converts it to water and oxygen rapidly. Factors affecting reaction P.H Concentration of Hydrogen Peroxide Temperature Concentration of catalyze in potato Prediction I think that the greater the surface area of catalyst the faster the reaction will occur, this is because there is more chance of the molecules colliding with each other because there are more enzymes and...
get a bung that sealed so it was all right. Instead of trying to use a conical flask, we could have used a gas syringe to collect the oxygen in. This would be more accurate because there is less chance of losing any oxygen, because it is a direct connection and unlikely to leak or move out of position. If we had more time we could of done some further experiments like, Using different potatoes, changing the concentration of the hydrogen peroxide, or changing the temperature the experiment was done at enzymes work best at 30 to 40c.

Rate Of Reaction in Sodium Thiosulphate and HCl Plan in this experiment I am investigating the rates of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of...

I will be investigating how the concentration of hydrochloric acid affects the rate of reaction between hydrochloric acid and magnesium ribbon. Equation: Mgs+2HClaq→MgCl2aq+H2g Planning: The input variables are: ?óÔé¼?ó temperature of acid ?óÔé¼?ó concentration of acid ?óÔé¼?ó surface area of magnesium ...

My aim is to find out whether temperature has an effect on a rate of the reaction. I am going to be using the example of the reaction between Sodium Thiosulphate and Hydrochloric Acid. Prediction I predict that the higher the temperature, the more quickly the...

Prediction I predict that the lower the concentration of the hydrochloric acid so there is fewer particles per cm3, the slower the rate of reaction will be. This is because there will be fewer particles in the Hydrochloric acid per cm3, and the solution will be more dilute so...
