For a chemical reaction in which, one of the reactant also acts as solvent, the order will be
Correct answer: D. Pseudo-first order
- A. First order
- B. Third order
- C. Second order
- D. Pseudo-first order
Explanation
If the reactant acting as the solvent is present in a vast excess compared to other reactants, the reaction can be approximated as a pseudo-first-order reaction. Therefore, option D is correct.

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.
