Question : 21
Total: 35
(a) The conversion of molecule A B B
(b) Define Pseudo first order reaction with an example
(b) Define Pseudo first order reaction with an example
Solution: 👈: Video Solution
(a) Reaction is A →
( Rate ) 1 = K [ A ] 2
( Rate ) 2 = K [ 3 A ] 2 = 9 K [ A ] 2
( Rate ) 2 = 9 × ( Rate ) 1
So the rate of formation ofB
(b) The reaction that have higher order true rate law but are found to behave as first order are known as pseudo first order reactions.
Example : Consider the acid hydrolysis of methyl acetate.
C H 3 C O O C H 3 ( a g ) + H 2 O ( e ) → C H 3 C O O H ( a g ) + C H 3 O H ( a g )
So the rate of formation of
(b) The reaction that have higher order true rate law but are found to behave as first order are known as pseudo first order reactions.
Example : Consider the acid hydrolysis of methyl acetate.
