Decomposition of N2O5 is an example of:
Correct answer: A. First order
- A. First order
- B. Second order
- C. Third order
- D. Zero order
Explanation
The decomposition of N2O5 follows first-order kinetics. This means that the rate of the reaction is directly proportional to the concentration of N2O5. As N2O5 decomposes, the rate of the reaction decreases over time because the concentration of N2O5 is decreasing.

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.
