WebThe speed of a reaction is given by the reaction rate, a measure of how fast reactants are consumed and products are formed. The study of reaction rates is known as chemical kinetics . The central theory of kinetics is collision theory. The premise of this theory is simple: molecules have to collide to react.

Heart rate is controlled beat by beat by the brain. Infact the native rate of the heart (the sinus nodal rythym) is around 100 beats per minute. The parasympathetic supply to the heart (through vagus nerve) supresses the rate to around 70-80. So if the parasympathetic flow is supressed, the heart rate will accelerate.
