If the reaction P+Q→R+ S is described as being of zero order w.r.t to P. It means that:
Correct answer: D. The rate of reaction is independent of conc. of P
- A. P is a catalyst in this reaction
- B. P molecules do not possess sufficient energy to react
- C. The rate of reaction is independent of conc. of Q
- D. The rate of reaction is independent of conc. of P
Explanation
If a reaction is of zero order with respect to P, it means that changes in the concentration of P do not affect the rate of the reaction. The rate is determined by other factors, not the concentration of P.

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.
