If the reaction 'P +Q → R+ S' is described as being of zero order with respect to P, it means that:
Correct answer: D. The rate of reaction is independent of the concentration of P
- A. P is catalyst in this reaction
- B. P molecules do not possess sufficient energy to react
- C. The concentration of P does not change during the reaction
- D. The rate of reaction is independent of the concentration of P
Explanation
Option d is correct because if a reaction is described as being of zero order with respect to a particular reactant (in this case, P), it means that the rate of the reaction is independent of the concentration of that reactant.

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.
