Factors affect rate decomposition hydrogen peroxide fixed

At the same time the stop-clock will be started. It is not possible, in this instance, to use a concentration of Hydrogen peroxide of more than Also my hair will be tied back and my tie Nill be tucked into my shirt.

Instead of changing the concentration, we could have done a weight loss. Fair Test ro ensure that this experiment is constant we will repeat the experiment.

This may have happened during our experiment, because whilst we were performing one experiment, the hydrogen peroxide was waiting in a conical flask for the next experiment. Less total product is obtained by the smaller concentrations: However, lg of manganese oxide seemed to be too much as the amount Sorry, but full essay samples are available only for registered users Choose a Membership Plan of gas was produced too quickly and we were unable to record any as again we were unable to record any results.

Surface area of catalyst grains- It is the contact surface area of a catalyst with a reactant that counts to catalyse a reaction. I will use the same concentration of hydrogen peroxide 2. Amount of catalyst used- Using more catalyst will mean that the catalyst meets the Hydrogen peroxide over a larger surface area to work on.

The Catalytic Decomposition Of Hydrogen Peroxide

The timing of the result may not have been correct or the reading of the amount of gas released may not have been accurate. This may have happened during our experiment, because whilst we were performing one experiment, the hydrogen peroxide was waiting in a conical flask for the next experiment.

For the main experiment; it is needed to measure the reaction over a time period of at least a few minutes and to have an easily measurable amount of Oxygen produced in order to be able to see how the reaction has progressed easily.

Therefore we can conclude that Manganese Dioxide is the most effective catalyst out of the available catalysts. In this experiment I will be looking at concentrations, temperatures and the affect of a catalyst.

And enzyme is a biological catalyst. Fair Test To ensure that this experiment is constant we will repeat the experiment. The amount of gas released was released at an even speed.

Manganese Oxide MnO It is very harmful if it is swallowed or inhaled.Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide.

I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide.

Factors affect the rate of the decomposition of hydrogen peroxide Essay Sample

What factors affect the rate of the decomposition of hydrogen Essay Under: Essays Prediction: I predict that the higher the concentration of hydrogen peroxide, the faster hydrogen eroxide and manganese oxide decomposes.

Factors Affecting Decomposition of Hydrogen Peroxide C) and pH () on the rate and extent of the decomposition of H2O2 were examined over a. Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance, which alters the speed, or rate of a chemical reaction but is chemically unchanged at the end of the reaction.

Pd catalysts on ACC, oxidized with nitric acid, are considerably less active in catalytic decomposition (H 2 O 2 → H 2 O + (1/2)O 2) and hydrogenation (H 2 O 2 + H 2 → 2H 2 O) of hydrogen peroxide than the corresponding ones on non-oxidized ACC.

P LANNING Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance, which alters the speed, or rate of a chemical reaction but is chemically unchanged at the end of the reaction.
