- A. Unit rate constant
- B. Specific rate constant
- C. Relative rate constant
- D. Average rate constant
Explanation

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
