Concentration Formula:
From: | To: |
Definition: This calculator determines the concentration of reactant A in a second-order irreversible chemical reaction where reactant concentrations are equal.
Purpose: It helps chemists and chemical engineers calculate reactant concentrations based on reaction kinetics.
The calculator uses the formula:
Where:
Explanation: The concentration is calculated as the square root of the reaction rate divided by the rate constant.
Details: Accurate concentration calculations are essential for reaction optimization, reactor design, and process control in chemical engineering.
Tips: Enter the reaction rate in mol/(m³·s) and the rate constant in m³/(mol·s). Both values must be positive numbers.
Q1: What is a second-order reaction?
A: A reaction where the rate is proportional to the product of the concentrations of two reactants or the square of one reactant's concentration.
Q2: When is this formula applicable?
A: For irreversible second-order reactions with equal initial concentrations of reactants.
Q3: What are typical units for k₂?
A: The rate constant typically has units of m³/(mol·s) for second-order reactions.
Q4: How is reaction rate determined experimentally?
A: By measuring the change in concentration over time under controlled conditions.
Q5: Can this be used for reversible reactions?
A: No, this calculator is specifically for irreversible reactions.
