Definition: This calculator determines the concentration of product B formed in a set of two parallel first-order reactions from reactant A.
Purpose: It helps chemists and chemical engineers predict product distribution in parallel reaction systems.
The calculator uses the formula:
Where:
Explanation: The formula accounts for the competition between two parallel reactions and their respective rates.
Details: Understanding product distribution is crucial for reaction optimization, selectivity control, and process design in chemical industries.
Tips: Enter all rate constants in 1/s, initial concentration in mol/m³, and time in seconds. All values must be > 0.
Q1: What are parallel reactions?
A: Parallel reactions occur when a reactant can form different products through two or more independent reaction pathways.
Q2: How do I determine the rate constants?
A: Rate constants are typically determined experimentally through kinetic studies of the individual reactions.
Q3: What if I have more than two parallel reactions?
A: The formula can be extended to include additional rate constants in the denominator and additional product terms.
Q4: Does this work for non-first-order reactions?
A: No, this formula is specific for first-order parallel reactions.
Q5: What does the exponential term represent?
A: It represents the fraction of reactant A that remains unreacted at time t.
