The rate of reaction can be calculated by calculating?
Correct answer: D. Change in concentration
- A. Change in temperature
- B. Change in pressure
- C. Change in volume
- D. Change in concentration
Explanation
Rate is the change in concentration per unit time. When the reactant is used up that means that the reaction is taking place. Hence, as the reactant is used up we can determine the rate at which the concentration of the reactant is used up hence we can determine the rate of reaction.

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.
