**Table 3: Enzyme Activity at Different Temperatures**

**ENZYME 1**

- **Temperature (C) | Product Formation (µmol)**
  - 0°C | 1.12 µmol
  - 10°C | 2.09 µmol
  - 20°C | 3.66 µmol
  - 30°C | 6.19 µmol
  - 40°C | 9.55 µmol
  - 50°C | 13.48 µmol
  - 60°C | 14.79 µmol
  - 70°C | 5.28 µmol
  - 80°C | 0.02 µmol
  - 90°C | 0.02 µmol
  - 100°C | 0.03 µmol

**ENZYME 2**

- **Temperature (C) | Product Formation (µmol)**
  - 0°C | 3.96 µmol
  - 10°C | 7.53 µmol
  - 20°C | 13.39 µmol
  - 30°C | 22.16 µmol
  - 40°C | 35.14 µmol
  - 50°C | 51.02 µmol
  - 60°C | 66.2 µmol
  - 70°C | 71.11 µmol
  - 80°C | 31.06 µmol
  - 90°C | 0.01 µmol
  - 100°C | 0.02 µmol

**Graph Explanation:**

The graph illustrates the product formation of Enzymes 1 and 2 over a range of temperatures (0-100°C). 

- **Enzyme 1 (black line)**:
  - The product formation gradually increases from 0°C, peaking at 60°C with 14.79 µmol, then sharply declines.
  
- **Enzyme 2 (blue line)**:
  - The product formation steadily rises, reaching a maximum at 70°C with 71.11 µmol, before rapidly decreasing.

**Question 7:**
At what temperature do you think both of these enzymes work best? How did you come up with your answer?

Expert Solution
Step 1 Introduction

An temperature increase increases the rate of reaction.

An increase in temperature raises the average kinetic energy of the molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision he temperature the rate of reaction increases.

For many reactions, the rate of reaction doubles for every 10°C rise in temperature.
