A reaction involving two different reactants can never be:

• A. unimolecular reaciton
• B. first order reaction
• C. second order reaction
• D. bimolecular reaction

Answer 1

The correct option is A unimolecular reaciton

A reaction involving two different reactants can never be unimolecular reaction.

This is because, for the reaction to occur, atleast two different molecules must collide.

In a unimolecular reaction, only one molecule is involved.
