Investigate the effect of changing the concentration of a catalyst on the rate of a reaction.
Introduction
We must produce a piece of coursework investigating the affect of changing the concentration of a catalyst on the rate of a reaction. The rate of reaction is a change in the concentration of a reactant or product per unit time. There are five factors, which can affect the rate of reaction, according to the collision theory of reacting particles:
* Temperature
* Concentration
* Pressure
* Surface area
* Catalyst
I have chosen to investigate the effect that different concentrations of catalyst (Copper sulphate) have on this reaction. I am going to record the Hydrogen given off in the solution.
Concentration:
The concentration of a substance, normally a solution, is the amount in a given volume.
Concentration= amount
volume
In a higher concentration solution there are more particles to react therefore there are more collisions. As a reaction depends on collisions happening, more collisions lead to faster reaction rate. If I was doing a reaction with acid and we double the number of collisions and therefore are likely to double the reaction rate.
Low concentration High concentration
Planning
I was given to work with:
Zinc (10x10 cm)
Sulphuric acid
Catalyst- Copper sulphate (solid/solution)
Zinc is 6th in the reactivity series, so it is a reactive metal, and reacts well with a dilute acid. The acid that I am going to use is sulphuric acid, and the catalyst is copper sulphate. The catalyst just speeds up the reaction happening between the zinc and the sulphuric acid.
