Given the chlorination of acetone shown below, choose the correct rate law. СНЗСОСНЗ + CI2 > СНЗСОСН2CI + HCI rate = [CH3COCH3] O rate = [C12] O rate [CH3COCH3][C12] %3! rate = [CH3COCH3][CI2]1/2 cannot be determined from stoichiometry; must be determined experimentally
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
![**Question 2**
**Given the chlorination of acetone shown below, choose the correct rate law.**
\[ \text{CH}_3\text{COCH}_3 + \text{Cl}_2 \rightarrow \text{CH}_3\text{COCH}_2\text{Cl} + \text{HCl} \]
- ○ rate = [CH₃COCH₃]
- ○ rate = [Cl₂]
- ○ rate = [CH₃COCH₃][Cl₂]
- ○ rate = [CH₃COCH₃][Cl₂]¹/²
- ○ cannot be determined from stoichiometry; must be determined experimentally
**Explanation:**
This multiple-choice question asks students to identify the correct rate law for the reaction of acetone with chlorine. Various rate expressions are given, reflecting different dependencies on the concentrations of acetone and chlorine. The correct answer requires an understanding that rate laws are typically determined through experimental data rather than stoichiometry alone.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fff118cbd-08fc-4eda-8b14-5c752c52beec%2Fda5905f4-2b8d-47fd-9dc3-edd50bea123a%2Fygmumo_processed.jpeg&w=3840&q=75)
