Force so the reaction is faster four factors which affect rates of reaction: surface area - surface area is the measure of how much exposed area a solid object has, expressed in square units temperature - heating chemical substances can make the molecules separate and move around faster this can increase the.

Rates of reaction gcse coursework chemistry 2004 aim in the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride the hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste corrode active.
Rhubarb rhubarb rhubarb this investigation looks at rates of reaction by using the reaction between oxalic acid in the rhubarb and potassium manganate vii as described, the investigation looks at concentration and surface area but temperature would be an easy addition rhubarb rhubarb - experiment guide. Chemistry report: experiment on rates of reaction 3605 words - 14 pages rates of reaction caco3 + 2hcl → cacl2 + h2o + co2 in this report i will be 1973 words - 8 pages rates of reaction - sodium thiosulphate and hydrochloric acid in this piece of coursework, i will study how concentration affects the rate of. To discuss rate cannot be directly measured, so instead chemists often measure the concentration of a reactant or volume of gaseous product as the reaction progresses look at the graphs below they are the concentration–time graphs for two different chemical reactions study each graph carefully and decide whether.
The more molecules in a chemical the more concentrated it is when a chemical has a greater concentration of molecules the chances of successful collisions increases and therefore speeds up the reaction catalyst adding a catalyst will speed up a reaction by decreasing the energy needed to break the bonds a catalyst.
