A reaction mechanism is defined as the sequence of reaction steps that define the pathway from reactants to products. Each step in a mechanism is an elementary reaction, which describes a single molecular event of usually one or two molecules interacting. The rate law for an overall reaction is the rate law for the slowest step in the mechanism, which is directly related to the stoichiometric coefficients of the reactants. The exception to this rule occurs when the slowest step...
PROBLEM 2 The elementary liquid phase irreversible reaction (A+B -> C) takes place in a 1 m² Mixed Flow Reactor with the equimolar mixture of A and B at the volumetric feed flow rate of 0.5 m3/min, the feed concentration of A equal to 1 mol/L, and the feed temperature of 300K. When the reaction takes place under isothermal conditions at 300K the conversion of A is 30%. When the reaction takes place adiabatically the exit temperature is 350K and...
