The mental and physical state of the smoker, and the situation in which smoking occurs, influence the way in which a cigarette affects psychological states and physiological responses.3. In order to provide a strong psychoactive reaction, nicotine must be delivered rapidly to the brain.
Redox Reactions Redox reactions, or oxidation-reduction reactions, have a number of similarities to acid-base reactions. Fundamentally, redox reactions are a family of reactions that are concerned with the transfer of electrons between species.
Reductionâ Oxidation Reactions. Unlike many nonredox reactions such as acid/base and precipitation reactions which involve. simple exchange of groups or ions of the reactants to form water or precipitates, the redox. reactions primarily involve the transfer of electrons between two elements in the reactants.
