The document discusses determining the rate constant for enzymatic reactions. It defines enzymes as proteinaceous biological catalysts that lower the activation energy of reactions and alter the reaction rate. The rate constant quantifies the rate of reaction, is denoted by k, is independent of concentration but reliant on temperature, and has no units. Determining the rate constant involves measuring the reaction rate under varying conditions as explained in a Khan Academy video.

2. What are Enzymes?
• Enzymes are macromolecular ,proteinaceous substances that alter the
rate of the reaction.
• They are also known as “Biological Catalysts” owing to their
composition and their analogy to catalysts.
• Enzyme kinetics is the study of the chemical reactions that
are catalyzed by enzymes. In enzyme kinetics, the reaction rate is
measured and the effects of varying the conditions of the reaction are
investigated.
• The hallmark of enzymes is that they lower the Activation Energy of the
reaction.
Note: “All Enzymes are catalysts but all catalysts are not enzymes.”

4. Rate Constant
• Rate Constant quantifies the rate of a chemical reaction.
• It is denoted by k or by the Greek letter lambda.
• It is independent of concentration but is reliant on
Temperature.
• It is not having any unit.

5. Explanation
• This is due to be done by the help of a video by Khan Academy.
