Identify the correct statements from the following:
I. The order of reaction is determined from experiment only
II.The order of reaction can be zero , positive integer or a fraction
III.In a multistep reaction, the slow step determines the rate
I. The order of reaction is determined from experiment only
II.The order of reaction can be zero , positive integer or a fraction
III.In a multistep reaction, the slow step determines the rate
Show Hint
- I, II, III
- I, II only
- II, III only
I, III only
The Correct Option is A
Solution and Explanation
Let's analyze the given statements:
Statement I: The order of the reaction is determined from experiment only.
This statement is correct. The order of a reaction cannot be predicted theoretically, and it must be determined experimentally based on reaction rates.
Statement II: The order of a reaction can be zero, a positive integer or a fraction.
This statement is also correct. The order of reaction can indeed be zero, a positive integer, or even a fraction, depending on the nature of the reaction.
Statement III: In a multistep reaction, the slow step determines the rate.
This statement is also true. In a multistep reaction, the slowest step, often referred to as the rate-determining step, governs the overall rate of the reaction.
Thus, all three statements are correct.
