SECTION - A
Answer the following questions (Do any two):
(a) Identify the order of reaction from the following unit for its rate constant:
(b) The conversion of molecules
(c) Write the expression of integrated rate equation for zero order reaction.
Solution:
(a) The unit L mol − 1 s e c − 1
(b) For reactionA → B
Rate of reaction( r )
= k [ A ] 2 . . . . .1
If the concentration of reactant increased to three times.
Rate of reaction( r ′ )
= k [ 3 A ] 2 . . . . .2
Thus, on dividing eq. 1 and 2 .
=
=
Therefore, rate of formation of B increases to nine times.
(c) Integrated rate equation for zero order reaction is
k =
Where,k =
R 0 = Initial concentration of reactant
R = Final concentration of reactant
t = time taken
(b) For reaction
Rate of reaction
If the concentration of reactant increased to three times.
Rate of reaction
Thus, on dividing eq. 1 and 2 .
Therefore, rate of formation of B increases to nine times.
(c) Integrated rate equation for zero order reaction is
Where,
