Do you have a Grade 10, 11 or 12 learner who is needing some help with their FET science practical experiment? We have put together some videos of some of the practicals and we will launch them each Thursday.
Temperature can affect the rate of a chemical reaction. In warmer temperatures, the molecules have more energy, move faster and thus will have more collisions with one another. This will, therefore, increase the reaction rate. The opposite is true in the case of colder temperatures.
This is one of the main reasons that we keep foods like dairy or fresh fruits in the refrigerator. The process of food spoilage by microorganisms is also a chemical reaction, so the cold temperature reduces the rate of reaction and keeps our foods fresh for longer.
