How does changing the concentration of the limiting substance affect the rate of reaction?

Substrate concentration is directly proportional to rate of reaction because more enzymes are able to act on it but this happen only until all the active sites are covered than reaction rate becomes constant.

What is the thing called that is completely used up in a reaction?
The limiting reagent (aka limiting reactant) is the substance which is completely used in a chemical reaction.
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid change throughout the course of a reaction decreases. This is because the substance is no longer pure.
How is the enzyme affected during the catalyzed reaction?
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
What equilibrium concentrations are affected by changing the initial concentration?
Yes, the concentrations are constant but not necessarily static. The 'forward' reaction rate matches the 'reverse' reaction rate.
How the limiting reactant control the product?
The yield of the reaction depends in this case only on the concentration of the limiting reactant.
What is the thing called that is completely used up in a reaction?
The limiting reagent (aka limiting reactant) is the substance which is completely used in a chemical reaction.
What is the procces of of substances changing into a new substance?
This would be a chemical reaction.
How is the effect of concentration changes on the reaction rate seen in the rate?
That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
What is the definition of a reactant concentration?
Reactant concentration is the exponent or index in which a substance's concentration term is increased in the rate equation. Reactant concentration is also known as the order of reaction.
What effect does changing the concentration on acid have in a chemical reaction invlving a metal such as magnesium?
Increasing the concentration of an acid would increase the rate and vigor of the reaction involving a metal such as magnesium.
What is a reactant?
A reactant is a substance that participates in and changes during a reaction.
What is called changing a particular substance into another particular substance?
The conversion of one substance to another substance is a chemical change, which happens as a result of a chemical reaction.
What is A method to determine the concentration of a substance in solution by adding a solution of known volume and concentration until the reaction is done?
The answer to my own question is: TITRATION
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid change throughout the course of a reaction decreases. This is because the substance is no longer pure.
Define limiting reactant?
In a chemical reaction the limitting reactant is also know as limiting reagent.it is the substance which is totally consumed when the chemical reaction is complete.the reacton can not proceed without it.
