WebAlso, kinetics is a very simple chapter and maximum of 2 questions can be asked from this chapter which are most probably numericals and it will take your little bit of more time if you have not practiced them. So , practise them as much as you can atleast all ncert questions . Good luck !! Rajat Garg WebGenerally, for a reaction of nth order, a graph of 1/ [A] n-1 vs t must be a straight line. Here [A] is the concentration of reactant at any given time of the reaction (other t =0). [A] = (a-x) where a is the initial concentration and x is the extent of reaction at time t. Refer to the following video for Determination of Order of a Reaction
Web7 okt. 2024 · The second-order reaction requires the determination of the concentration of both the present reactants together. The pseudo-first-order reaction method helps in the study of chemical kinetics. Example: CH 3 COOCH 3 + H 2 O → CH 3 COOH + CH 3 OH. This reaction follows pseudo-first-order kinetics because water is present in a …
