In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
The starting (or beginning) substances in a chemical reaction are called reactants.
substrate
Substrates
before reaction = reactants after reaction = products
The chemicals which are involved in a reaction are called Reagents or Reactants
pH Temperature Ionic Strength Aw Substrate Concentration Substrate location.
increasing the concentration increases the rate of the reaction
I would point your studies towards collision theory. It's not that a low concentration necessarily slows down a reaction, but that a low concentration will have a slower reaction rate than a higher concentration of reactants. A lower concentration means a lower number of reactants in solution, meaning it is less likely for the reactants to collide and create products. With a lot of reactants, it is much more likely for collisions to occur.
The reactants
The substances you have at the beginning of a chemical reaction are called the reactants.
The starting materials in a chemical reaction are called reactants.
The terms reactant and product can be used to describe constituents of individual enzymatic reactions or entire metabolic pathways. Reactants (or 'substrates') are the starting materials for a reaction, products are the result of the chemical reaction.

The reactants exist before a reaction begins, and also the products are the result of the reaction of the reactants.
The substances that are combined in a chemical reaction are called the reactants, and the end substances are called the products.Compounds involved in a process but not found in the end products are called catalysts.
Chemical Reaction
A reactant or reactants enters into a chemical reaction to form product(s)
The reactants
This is known as an enzymatic reaction.
The substances used up in a reaction are the reactants. The new substances made are called the products. The terms reactant and product can be used to describe constituents of individual enzymatic reactions or entire metabolic pathways. Reactants (or 'substrates') are the starting materials for a reaction, In the generic reaction shown below, A and B are the reactants. C and D are the products. http://www.marietta.edu/~spilatrs/biol103/photolab/reaction.html image reference
