Extended Practical Investigation: The Catalysis Of

Extended Practical Investigation
The catalysis of the reaction in the midst of surface and sulphuric acid

The energizing pushing of the reaction result be estimated using experimental data, a catalyst will be added and the activating energies will be comp bed to see if the catalyst has had an establish on this.

Aims and objectives
The effect of adding a copper catalyst to the reaction between zinc and sulphuric acid on the activation push button will be investigated. The effect of copper as a catalyst on the point of the reaction will be observed and the Arrhenius par will be used to count the activation cipher.
Background
Acids react with some metals to produce a metal salt and hydrogen gas. atomic number 30 reacts with sulphuric acid, producing hydrogen gas.
Zinc + Sulphuric acid ? Zinc sulphate + Hydrogen
Zn(S) + H2SO4(aq) ? ZnSO4(aq) + H2(g)
For the reaction to occur, bonds are broken whilst others are made. Energy is required in golf club for this process to take place. Whilst reactions roll in the hay be exothermic or endothermic when particles from different molecules collide they may not feature enough energy to break the appropriate bonds.



The reaction can only take place if the colliding particles possess enough energy to break and make new bonds; this is known as the activation energy.
Only a fraction of particles in this reaction will have energy greater than the activation energy. This is given by the expression e-EA/RT, e is the exponential function, R is the gas never-ending and T is the absolute temperature. This means at a specify temperature the reaction rate depends on how many particles have the activation energy. K is known as the rate constant for the rate of reaction if this is dependent on the particles that have the required energy then k is proportional to the EA.
K= Ae-EA/RT
The above is the Arrhenius equation and...If you want to get a full essay, order it on our website: Orderessay
