WebbEffect of temperature on reaction rate. Over a period of time, enzymes will be deactivated at even moderate temperatures. Storage of enzymes at 5°C or below is generally the most suitable. Lower temperatures lead to slower chemical reactions. Enzymes will eventually become inactive at freezing temperatures but will restore most of their enzyme ... WebbThe rate of the reaction is dictated by the slowest elementary step of the reaction. This step is called the “rate-determining step“. No matter how fast the speed of the other elementary steps are, the reaction cannot go faster than the slowest step. The diagram above is called a reaction coordinate diagram or energy profile diagram.
