Definition: This calculator determines the equilibrium concentration of reactant B in a chemical reaction using rate constants and other equilibrium concentrations.
Purpose: It helps chemists and chemical engineers analyze reaction equilibria and predict reactant concentrations in reversible reactions.
The calculator uses the formula:
Where:
Explanation: The formula relates the equilibrium concentrations through the ratio of rate constants.
Details: Accurate equilibrium calculations are crucial for reaction optimization, process design, and understanding chemical systems.
Tips: Enter all required values with correct units. Default values are provided for demonstration. All concentrations must be ≥ 0, and rate constants must be > 0.
Q1: What units should I use for rate constants?
A: The calculator uses m³/(mol·s) for both forward and backward rate constants.
Q2: Can I use concentrations in mol/L instead of mol/m³?
A: Yes, but be consistent - all concentrations must use the same units.
Q3: What if my reaction has different stoichiometry?
A: This calculator is for reactions of the form A + B ⇌ C + D. Different stoichiometry requires formula modification.
Q4: How do I determine the rate constants?
A: Rate constants are typically determined experimentally through kinetic studies.
Q5: Does this account for temperature effects?
A: No, the calculator assumes constant temperature. Rate constants are temperature-dependent.
