Intermediate Concentration Formula:
From: | To: |
Definition: This calculator determines the concentration of intermediate product (CR) in a two-step first-order irreversible reaction series in a mixed flow reactor.
Purpose: It helps chemical engineers design and analyze reactors for consecutive reactions where an intermediate product is formed.
The calculator uses the formula:
Where:
Explanation: The formula accounts for both reaction steps and the residence time in the mixed flow reactor.
Details: Accurate calculation of intermediate concentration is crucial for optimizing reactor design, maximizing desired product yield, and minimizing unwanted byproducts.
Tips: Enter all required parameters with positive values. The calculator will compute the intermediate concentration (CR) in mol/m³.
Q1: What is space time in a mixed flow reactor?
A: Space time (τm) is the time required to process one reactor volume of feed under specified conditions.
Q2: How do rate constants k1 and k2 affect the result?
A: Higher k1 increases intermediate formation, while higher k2 decreases it by converting the intermediate to final product faster.
Q3: What if I get negative or zero values?
A: All input values must be positive. The calculator validates this before computation.
Q4: Can this be used for batch reactors?
A: No, this formula is specifically for mixed flow (CSTR) reactors. Batch reactors have different kinetics.
Q5: How accurate is this calculation?
A: It's theoretically exact for ideal mixed flow reactors with first-order irreversible consecutive reactions.
