Question

# 1. What overall reaction order corresponds with a rate constant with units s^–1? 2. What overall reaction order corresponds with a rate constant with units of M∙s^–1? Thank you! :)

Answer

s^-1 corresponds to first order reaction, M∙s^-1 corresponds to second order reaction

- Q:What is the definition of reaction order? A:Reaction Order is the sum of the powers (exponents) of the concentration terms in the rate equation.
- Q:What is the unit of the rate constant for the zero order reaction? A:For Zero-order reaction, the unit of Rate Constant is concentration per unit time (e.g M/s).
- Q:What is the unit of the rate constant for the first order reaction? A:For First-order reaction, the unit of Rate Constant is reciprocal of time (e.g 1/s).
- Q:What is the unit of the rate constant for the second order reaction? A:For Second-order reaction, the unit of Rate Constant is concentration per unit time (e.g M^-1 s^-1)
