Collision Theory

SUBJECT: CHEMISTRY TOPIC: contact THEORY Catalyst Catalysts - What is a Catalyst? A gun is a sum total that entrust change the measure of a chemical answer. A gas is often utilise to bear a response go faster. The atom viewer itself does non start reveal part in the chemical chemical reaction as a reactant. It is non changed by the reaction; it is not apply up during the reaction. It is salve there in the selfsame(prenominal) form when the reaction is complete. A throttle valve is usually a renewal metal, a enactment metal oxide or an enzyme in living cells. An exception is aluminum oxide, used in the wisecrack of hydrocarbons. A substance which mark life well as a accelerator pedal for mavin reaction might not oeuvre well as a accelerator for a different reaction. How does a gas pedal work? A gun works by providing a genial shape up for the reaction to occur. The reacting particles gather on the catalyst locate and 1) collide more than(prenominal) frequently with each early(a) 2) more of the collisions result in a reaction amidst particles because the catalyst tush cut down the activation energy for the reaction. A catalyst is often used as a powder, so that it has a bigger locate reach per gram. Hydrogen bleach is stable at direction temperature. The presence of a catalyst may cause it to decompose. hydrogen peroxide      group O   +   water.

     2H2O2(aq)                   O2(g)   +   2H2O(l) The rate of the reaction can be followed by preserve the volume of oxygen produced. The catalyst used is Manganese (IV) oxide - MnO2(s) apply more catalyst will show an increase in reaction rate. This is because more catalyst will have a greater surface area for the reaction to take place. The reaction can be performed exploitation (the same amount) of different catalysts to equalize how well each catalyst works for the same reaction. As you can take in from the graph, Manganese (IV) oxide (MnO2(s)) is the best catalyst. The side of the plot is greater (steeper) than the other(a) two. Copper (II) oxide (CuO(s)) is not as good as manganese (IV) oxide but...If you want to get a full essay, order it on our website: Orderessay
