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.

![### Reaction Rate Law Question
**Question 1B:** What is the rate law for the reaction of 2-Methyl-1-phenyl-2-propanol with HBr? What compound(s) does the rate of the reaction depend on?
---
**Explanation:**
The rate law for a chemical reaction describes the relationship between the reaction rate and the concentration of the reactants. It is typically expressed in the form:
\[ \text{Rate} = k [\text{Reactant 1}]^m [\text{Reactant 2}]^n \]
where:
- \( k \) is the rate constant,
- \( [\text{Reactant 1}] \) and \( [\text{Reactant 2}] \) are the molar concentrations of the reactants,
- \( m \) and \( n \) are the reaction orders with respect to each reactant.
In this specific reaction:
- **Reactants:** 2-Methyl-1-phenyl-2-propanol and HBr.
To determine the rate law, the dependency of the reaction rate on each of the reactants' concentrations must be identified. This can be done through experimental observation or provided data.
If additional information, such as experimental data or a mechanism, is provided, it would typically detail the steps to derive the rate law and the compound(s) that influence the reaction rate.
As there are no graphs or diagrams in the original image, none are described here.

- **Order of Reactions**
- **Rate-Determining Steps in Mechanisms**
These resources can help clarify how to experimentally determine the value of \( k \), and the order of the reaction with respect to each reactant, hence forming the complete rate law.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb9b51b7-8e30-472f-a9b1-c9ee115779d7%2Fcab1497d-859e-4959-8747-1e4cad31668e%2Fxl93rh_processed.png&w=3840&q=75)
