For a reaction 2A + 3B -> CThe rate law expression is given by rate = K [A]1[B]2. The order of the reaction with respect to A, B and overall order of reaction are:
Correct answer: B. 1, 2, 3
- A. 2, 1, 3
- B. 1, 2, 3
- C. 0, 1, 2
- D. 2, 1, 0
Explanation
The rate law expression is = K [A]1 [B]2 The order of the reaction with respect to A and B s 1 and 2 respectively. The overall order of the reaction is 1 + 2 = 3 Hence, the correct option is B.

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.
