An experiment suitable for gcse science investigating the effect of concentration and temperature on the rate of reaction. A powerpoint on effect of surface area on rates of reaction with supporting exam questions worksheet. 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.
Anjelina qureshi mrs gravell rates of reaction coursework chemistry year 11 rates of reaction introduction a chemical reaction occurs when things change from reactants into products these reactions only happen if the reacting molecules collide properly the rate of reaction is the speed of a reaction when the solution.

What is rate rate is a measure of how fast or slow something is in chemistry, we speak of a rate of reaction, this tells us how fast or slow a reaction is why do chemists want to know the rate of a reaction if you are making a product, it is important to know how long the reaction takes to complete, before the product is.
