WebSep 7, 2024 · Discuss. Pseudo means fake or false. A pseudo-first-order reaction is defined as a reaction that appears like a higher order reaction but is actually of a lower order. A pseudo-first-order reaction is a bimolecular reaction that appears like a first order (1st order) reaction due to more concentration of reactants than the other reactants. WebIn a first order reaction the reaction rate is proportional to the concentration of the reactant. So a graph of rate of reaction against concentration is a straight line with a positive gradient (a graph showing proportionality). A first order concentration-time graph has a constant half-life.
