Experiment | Initial rate of formation of | ||
0.1 0.3 0.3 0.4 | 0.1 0.2 0.4 0.1 |
Answer:
?(i)
?(ii)
On comparison, we get
[1]
Then,
Thus,
Thus, rate law is
From any experiment
[1]
Or
(a) Pseudo first order reaction Certain reactions which are biomolecular follow first order kinetics as concentration of one of the reactants is very high and does not change appreciably and also slow step (rate-determing step) involves only one reactant. Such types of reactions are called pseudo first order reactions.
Examples
(i) Hydrolysis of ester by acid
Water is present in large excess and its concentration does not change and
[1]
(ii)
[1]
By slow step
(b)
Given,
Thus, [1]
For energy of activation
