CBSE Class 12-science Answered
Sir,
can you please tell me that how to find the order of reactants while calculating order of reaction. Suppose a reaction
in this reaction how do we know the order of reactants????????????????

Dear jepankajyadav123@rediffmail.com
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
The reaction rate law expression relates the rate of a reaction to the concentrations of the reactants.
aA + bB → cC + dD
Rate = k [A]x [B]y
x and y are the reactant orders determined from experiment. x and y are NOT the stoichiometric coefficients. The rate law is always determined experimentally. There are several ways to determine the rate law for a particular reaction like ‘Method of Initial Rates’ and ‘Isolation Method’.
In the hydrolysis of ethyl acetate water is added in excess so the rate is dependant only on the concentration of ethyl acetate so it is a first order reaction w.r.t to ethyla acetate.
