The change in concentration of reactants or products per unit time is called:
Correct answer: C. Rate of a reaction
- A. Rate constant
- B. Reaction speed
- C. Rate of a reaction
- D. All of these
Explanation
Rate of reaction is typically expressed as the change in the concentration of reactants or products per unit time and is influenced by factors like temperature, concentration, and catalysts.

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.
