Definition: This is the highest concentration of intermediate product achieved in a two-step reaction where the first step is first order and the second step is zero order.
Purpose: It helps chemical engineers and researchers determine the optimal conditions for maximizing intermediate product yield in consecutive reactions.
The calculator uses the formula:
Where:
Explanation: The formula calculates the peak concentration of the intermediate product R in a consecutive reaction scheme A → R → S.
Details: Knowing the maximum intermediate concentration helps in designing reactors and optimizing reaction conditions when the intermediate is the desired product.
Tips: Enter the initial reactant concentration, zero order rate constant, and first order rate constant. All values must be > 0.
Q1: What types of reactions does this apply to?
A: This applies specifically to consecutive reactions where the first step is first order and the second step is zero order.
Q2: How do I determine the rate constants?
A: Rate constants are typically determined experimentally through kinetic studies of the individual reaction steps.
Q3: What if my reaction has different orders?
A: Different formulas apply for different reaction orders. This calculator is specific to first→zero order consecutive reactions.
Q4: What units should I use?
A: Use consistent units: mol/m³ for concentrations, mol/m³·s for zero order rate constant, and 1/s for first order rate constant.
Q5: Can this be used for batch or flow reactors?
A: The formula applies to ideal batch reactors or plug flow reactors where there's no back-mixing.
