Chemistry coursework Background knowledge Some reactions are fast and some are slow. For example; when silver nitrate is mixed with sodium chloride, a very fast reaction occurs, whereas rust forming on a heap of scrap iron is usually a very slow reaction. In order for reactions to take place; the particles must collide with each other, and the collision must have enough energy. The energy is normally given to the particles in heat. If there are lots of successful collisions in a given minute, then a lot of hydrogen is produced in that minute. I.e. the reaction goes quickly - its rate is high. If there are not many then its rate is low. Therefore the rate of reaction depends on how many successful collisions there are in a given unit of time. Why rate increases with concentration. If the concentration of an acid is increased, the reaction goes faster. Consequently if acid...
