2A + B → Product If the reactant 'B' is in excess, the order of reaction with respect to 'A' in given rate law is: Rate = k[A]2[B] is:
Correct answer: A. 2nd order reaction
- A. 2nd order reaction
- B. 1st order reaction
- C. Pseudo 1st order reaction
- D. 3rd order reaction
Explanation
Rate equation is mentioned and in case rate equation, especially order of reaction, is mentioned, then those are the only things to be considered. In this case, oder of reaction is 2+0=2 (SECOND ORDER).

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.
