Question

Which of the following statement is incorrect?
[NCERT Pg. 97]
(1) Average rate of reaction and instantaneous
rate of reaction are always different
(2) Stoichiometry of a reaction tells about the order
of the elementary reaction
(3) Rate of chemical reactions is independent of
molecularity of reactions
(4) In multistep reactions, the rate determining
step is the slowest step of the reaction​

Answer 1

Ans is option 1

Explanation:

For a short period of time avg and instantaneous rate of reaction is equal

rate of reaction depends on order of reaction and order depends on molecularity .
