1. What is Concentration of Radical in Chain Reaction?

Definition: This calculator determines the concentration of radicals formed during the chain propagation step of a chain reaction.

Purpose: It helps chemists and chemical engineers understand and predict radical concentrations in chain reactions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ [R]_{CR} = \frac{k_1 \times [A]}{k_2 \times (1-\alpha) \times [A] + k_3} \]

Where:

Explanation: The formula calculates radical concentration by considering the balance between radical formation and consumption.

3. Importance of Radical Concentration Calculation

Details: Understanding radical concentration is crucial for controlling reaction rates, predicting product distributions, and ensuring reaction safety.

4. Using the Calculator

Tips: Enter all required parameters with appropriate units. Default values are provided for typical chain reactions.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical value for k₁?
A: Initiation rate constants typically range from 10⁻⁷ to 10⁻³ m³/(mol·s) depending on the reaction.

Q2: How does α affect the radical concentration?
A: Higher α values (more radicals formed) generally lead to higher radical concentrations.

Q3: What units should I use for concentration?
A: The calculator uses mol/m³ for all concentrations. Convert from other units if necessary.

Q4: Can this calculator be used for polymerization reactions?
A: Yes, it can be adapted for radical polymerization by adjusting the parameters appropriately.

Q5: What if I get negative values?
A: Check your input values, especially α which should normally be ≥ 0.
