Rates of Reaction
Experiment: Investigation into the factors that effect the rate of reaction I am going to investigate how different factors affect the rate of a reaction. Introduction What is a reaction? A reaction is when two particles (reactants) join to form a new product or products. What is rate? Rate is a measure of how fast or how slow something is. Rate is a measurement of the change that happens in a single unit of time,

An Investigation into the Factors Affecting the Rate of the Reaction Between Calcium Carbonate and Hydrochloric Acid
An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: Ў¤ changing the surface area of any solids involved Ў¤ changing the concentration of reactants

Rate of Reaction
We are trying to find out if temperature affects the rate of reaction between Hydrochloric acid and Magnesium. I think that the higher the temperature of the acid rises, the rate of reaction will increase. For example: If I double or triple the reaction, the rate of reaction will also double or triple. As the liquid particles bash into the solid they may knock of a solid particle. This collision would therefore cause a reaction.

Rates of Reaction
Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur, the equation for this reaction is: Na2 S2 O3 + HCL, H2 O + NaCL + SO2

To Investigate the Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid
Aim: To investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride, Water and Carbon Dioxide. The symbol equation for this is: CaCo3  Ca2+ + Co32- Hcl  H+ + Cl- Add these all together

What Effect the Concentration of Acid Has on the Rate of Reaction
The Effect of concentration on the rate of reaction Aim The aim of this experiment is to find out what effect concentration has on a rate of reaction. Prediction I predict that the higher the concentration of the acid, the faster the reaction will take place, this is because when there is a higher concentration, to a certain extent, there is more particles, so the higher the concentration of acid, the more particles there would
