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

Hypothesis The place of a answer is the speed up at which a reply observes. If a chemical reaction has a modest rate, that fashion the molecules combine at a sulky speed than a reaction with a high rate. Some reactions strike hundreds, peradventure even thousands of years while other rat happen in less than unity second. The rate of reaction depends on the type of molecules that atomic number 18 combining. There are dickens workable ways of measuring a rate: prize how quickly atomic number 53 of the products are made, measure how quickly one of the reactants disappear. The theory that we use to formulate how different variables change everyplace the rate of reaction is called the collision theory. For a reaction to light upon place, the particles of the bone marrows that are reacting have to collide. Only a certain dissever of the total collisions cause chemical change; these are called undefeated collisions. The successful collisions have sufficient hefti ness (activation faculty - Ea) at the moment of impact to break the exist bonds and form refreshing bonds, resulting in the products of the reaction. The variable heat for voice causes the particles to gain energy this causes higher gamble 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 in that respect 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 molecules bounce some a megabucks more (because they have more energy). When they bounce around more, they are more...
