How do you determine the order of the reaction?
In order to determine the reaction order, the power-law form of the rate equation is generally used. The expression of this form of the rate law is given by r = k[A]x[B]y.How many methods are there to determine order of reactions?
There are at least four different methods to determine the order of a reaction. (1) Using integrated rate equations The reaction under study is performed by taking different initial concentrations of the reactant (a) and noting the concentration (a – x) after regular time intervals (t).How will you determine the order of reaction by differential and half life method?
If an increase in reactant increases the half life, the reaction has zero-order kinetics. If it has no effect, it has first-order kinetics. If the increase in reactant decreases the half life, the reaction has second-order kinetics.
