1. What is Initial Reactant Concentration for First Order Rxn in MFR?

Definition: This calculator determines the initial reactant concentration needed to achieve the maximum intermediate concentration in a mixed flow reactor (MFR) for two consecutive first-order reactions.

Purpose: It helps chemical engineers optimize reactor design and operation for consecutive reactions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ CA0 = CR_{max} \times \left(\left(\left(\frac{k2}{kI}\right)^{1/2} + 1\right)^2\right) \]

Where:

Explanation: The formula calculates the required initial concentration based on the kinetics of the consecutive reactions.

3. Importance of This Calculation

Details: Accurate calculation ensures optimal reactor performance and helps achieve desired product yields in consecutive reactions.

4. Using the Calculator

Tips: Enter the maximum intermediate concentration and both rate constants. Default values are provided for typical cases.

5. Frequently Asked Questions (FAQ)

Q1: What is a mixed flow reactor (MFR)?
A: Also known as CSTR, it's a reactor where contents are perfectly mixed and uniform throughout.

Q2: Why is maximum intermediate concentration important?
A: It helps determine the optimal conditions for producing intermediates in consecutive reactions.

Q3: How do rate constants affect the calculation?
A: The ratio of rate constants determines the required initial concentration to achieve maximum intermediate concentration.

Q4: What units should I use?
A: Use consistent units - mol/m³ for concentrations and 1/s for rate constants.

Q5: Can this be used for other reactor types?
A: This specific formula applies to MFR/CSTR reactors only.
