5. Frequently Asked Questions (FAQ)

Q1: What is the Arrhenius equation?
A: The Arrhenius equation describes how reaction rates depend on temperature and activation energy.

Q2: Why is this specific to second-order reactions?
A: Second-order reactions have different units for the rate constant (m³/(mol·s)) compared to first-order reactions.

Q3: What are typical values for activation energy?
A: Most chemical reactions have activation energies between 50-250 kJ/mol.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact, but real-world systems may deviate due to non-ideal behavior.

Q5: Can I use different units?
A: The calculator uses SI units. Convert your values to J/mol for energy and m³/(mol·s) for rate constants before input.
