Definition: This calculator determines the change in number of moles of reactants or products in a chemical reaction based on reaction rate, reactor volume, and time interval.
Purpose: It helps chemical engineers and researchers quantify reaction progress and design appropriate reactor systems.
The calculator uses the formula:
Where:
Explanation: The reaction rate multiplied by reactor volume gives moles per second, which when multiplied by time gives total moles changed.
Details: Accurate mole change calculation is crucial for reaction yield prediction, reactor design, and process optimization in chemical industries.
Tips: Enter the reaction rate in mol/m³·s, reactor volume in m³, and time interval in seconds. All values must be > 0.
Q1: What units should I use for the reaction rate?
A: The standard unit is mol/m³·s, but make sure all units are consistent in your calculations.
Q2: How do I determine the reaction rate?
A: Reaction rates are typically determined experimentally or from kinetic studies of the specific reaction.
Q3: Does this work for batch and continuous reactors?
A: This calculation applies to both, but interpretation differs - for continuous reactors, Δt would represent residence time.
Q4: Can I use this for gas-phase reactions?
A: Yes, but ensure your reaction rate is properly defined for gas-phase systems (may need pressure/temperature corrections).
Q5: How does this relate to reaction conversion?
A: The change in moles can be used with initial moles to calculate fractional conversion of reactants.
