Q
Q: Which of the following statements about reaction mechanisms is true?
Solution:
The rate-determining step is indeed the slowest step in a reaction mechanism, which controls the overall rate of the reaction.
Steps: 5
Show Steps
Step 1: Understand what a reaction mechanism is. It is the series of steps that occur during a chemical reaction.
Step 2: Identify the different steps in a reaction mechanism. Each step can have a different speed.
Step 3: Recognize that the rate-determining step is the slowest step in the mechanism.
Step 4: Know that the slowest step controls how fast the overall reaction happens.
Step 5: Conclude that the statement about the rate-determining step being the slowest step is true.
