Zero Order Reaction: A type of chemical reaction where changing the concentration of reactants doesn't affect the rate at which products are formed.
Pseudo First Order Reaction: A complex reaction that behaves like a first-order reaction because one reactant is present in such large quantities that its concentration hardly changes during the course of the reaction.
Arrhenius Equation:An equation that gives the dependence of the rate constant 'k' of a chemical reaction on temperature and activation energy.
