Rate of Reaction What affects the rate of reaction? Hypothesis To form a reaction the particles must collide in high speed. The faster the particles collide the more kinetic energy is produced. This produces a bigger reaction. There are five key variables that affect the rate of a reaction (in this case with a solid and a solution): * Change in temperature An increase in heat energy within the particles leads to more kinetic energy. Therefore there is more collision of particles and it increases the rate of the reaction. When we decrease the amount of heat energy, this will evidently slow down the reaction. For example we slow down the process of our food rotting by placing it in a fridge or a freezer. * Change in concentration The concentrations of acids are classed in molars, so 2m would quite a strong concentrated acid, 0.5m would be a very dilute weak acid and 1m would be...
