FAQs
Q1. What is a rate constant in chemical kinetics?
A rate constant (k) quantifies the speed of a chemical reaction and is specific to reaction conditions such as temperature and reaction order.
Q2. Which reaction orders are supported by this calculator?
Most calculators support zero-order, first-order, and second-order reaction kinetics.
Q3. Does the rate constant depend on concentration?
No, the rate constant is independent of reactant concentration but depends on temperature and reaction conditions.
Q4. Can this calculator be used for competitive exams?
Yes, it is highly useful for IIT-JEE, NEET, university exams, and chemistry coursework.
Q5. Is the Arrhenius equation used in this calculator?
Some advanced versions incorporate Arrhenius parameters to calculate temperature-dependent rate constants.
