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.
Describing the overall electrochemical reaction for a redox process requires a balancing of the component half-reactions for oxidation and reduction. In general, for reactions in aqueous solution, this involves adding H +, OH â, H 2 O, and electrons to compensate for the oxidation changes.
