WebThe starting substances in a reaction are the reactants, and the substances produced at the end of a reaction are called products. Some chemical reactions are so slow that you can’t observe a change right away (such as the formation of rust on a piece of metal), and … WebSo vision requires lots of steps, some of which are slow, to convert light to bioelectrical signals, meaning the visual reaction times can never be faster than about 150ms. Auditory signals require only one or two steps to become biological, and they are all generally fast. Thus auditory reaction times can be as fast about 70ms.

WebSome are moving fast some are moving slowly, and most are moving at some intermediate speed. Increasing the temperature by say 10°C causes some of the intermediate speed molecules to move faster. The result is more molecules with sufficient kinetic energy to form an activated complex upon collision! WebSlow Reactions. Given enough time, any reaction in a closed system should reach an equilibrium. However, enough time may be a very long time. Some reactions are so slow that they will never appear to reach an equilibrium. For example, a mixture of natural gas and oxygen.
