A reagent is something which is used to initiate a reaction and aids to carry out it and it is also consumed in a reaction, unlikely to catalysts which are not consumed in a reaction.

They are the starting materials for a reaction and are always found at the left side of a chemical equations.A reactant is one of the inputs in a reaction, that get changed. The word reactant is used in chemistry. A substance that has a reaction and undergoes a change is considered reactant.hey are the starting materials for a reaction and are always found at the left side of a chemical equations.
