-d[N2O5]/dt represents
Correct answer: B. (b) Rate of decomposition of N2O5
- A. (a) Rate of formation of N2O5
- B. (b) Rate of decomposition of N2O5
- C. (c) Order of the reaction
- D. (d) None.
Explanation
The correct answer is:(b) Rate of decomposition of N2O5Here's why the other options are incorrect:(a) Rate of formation of N2O5: The sign (-) before d[N2O5]/dt indicates a decrease in concentration, implying decomposition, not formation.(c) Order of the reaction: d[N2O5]/dt represents the rate of the reaction, but it does not provide information about the specific order of the reaction.(d) None: -d[N2O5]/dt is a commonly used notation in chemical kinetics to represent the rate of decrease in concentration of the reactant N2O5, directly translating to the rate of its decomposition.Therefore, considering the negative sign and focusing on N2O5, the expression clearly refers to the rate of decomposition of N2O5.

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.
