At which of the following temperatures is the speed of a given chemical reaction the fastest? 10 °f 20 °f 30 °f 40 °f

Generally speaking, the rate of a chemical reaction depends on a number of variables including temperature. The rate of a reaction is proportional to the temperature, as the temperature increases, the rate of reaction will increase. The reason being for this is that for the reaction to take place, the molecules must interact with one another in the form of collisions. As the temperature increases, energy is being added to the system which is absorbed by the molecules resulting in an increase in the velocity of these particles. The molecules begin moving must faster as temperature increases and this ultimately leads to more collisions between particles. An increase in collisions will allow more individual reactions to occur and this will lead to an increase in the rate of the reaction.

Therefore, the speed of a given chemical reaction will occur the fastest at 40 °F.
