G.C.S.E chemical reaction - rates of reaction between sodium thiosulphate solution and hydrochloric acid.

Hypothesis The place of a chemical chemical answer is the focal ratio at which a reaction observes. If a reaction has a woeful rate, that fashion the molecules combine at a laggard speed than a reaction with a high rate. Some reactions topic hundreds, peradventure even thousands of years while other spate happen in less than unity second. The rate of reaction depends on the type of molecules that argon combining. There be ii workable ways of measuring a rate: judge how quickly single of the products are made, measure how quickly one of the reactants disappear. The theory that we use to formulate how different variables change everywhere the rate of reaction is called the collision theory. For a reaction to let place, the particles of the shopping malls that are reacting have to collide. Only a certain separate of the total collisions cause chemical change; these are called roaring collisions. The successful collisions have sufficient heftiness (activation pus h button - Ea) at the moment of impact to break the exist bonds and form in the raw bonds, resulting in the products of the reaction. The variable heat for voice causes the particles to gain energy this causes higher run into for the particles to collide into individually other.

There are four main variables that could change the rate of a reaction: The concentration of the substance reacting - If at that place is more of a substance in a system, there is a greater chance that molecules will collide and speed up the rate of the reaction. If there is less of something, there will be fewer collisions and the reaction will probably happen at a slower speed. The temperature - When you raise the temperature of a system, the molec! ules bounce some a rush more (because they have more energy). When they bounce around more, they are more...
