Which of the following describes a ‘pseudo-first-order’ reaction?

A. All reactants are in excess
B. One reactant is in much higher concentration than others
C. The reaction occurs in multiple steps
D. It is a zero-order reaction

Answer: One reactant is in much higher concentration than others


Additional Information: In pseudo-first-order reactions, one reactant's concentration is significantly higher than the others, allowing the reaction to behave like first-order.
