Disulfiram-alcohol reaction (DAR) is the effect of the interaction in the human body of alcohol drunk with disulfiram or some mushrooms. [ 1 ] [ 2 ] The DAR is key to disulfiram therapy that is widely used for alcohol-aversive treatment and management of other addictions (e.g. cocaine [ 3 ] [ 4 ] use).
That is, r −1 ≪ r 2, so that r 1 − r 2 ≈ 0. But the overall rate of reaction is the rate of formation of final product (here CO 2), so that r = r 2 ≈ r 1. That is, the overall rate is determined by the rate of the first step, and (almost) all molecules that react at the first step continue to the fast second step.
A = (e 2 k B T/h) (RT/p) exp(ΔS ‡ /R). In these equations e is the base of natural logarithms, h is the Planck constant, k B is the Boltzmann constant and T the absolute temperature. R′ is the ideal gas constant. The factor is needed because of the pressure dependence of the reaction rate. R′ = 8.3145 × 10 −2 (bar·L)/(mol·K). [1]
In chemistry, a reaction step of a chemical reaction is defined as: "An elementary reaction, constituting one of the stages of a stepwise reaction in which a reaction intermediate (or, for the first step, the reactants) is converted into the next reaction intermediate (or, for the last step, the products) in the sequence of intermediates between reactants and products".

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [ 1 ] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction.
