∙ 15y agoGenerally speaking, a reactant's consumption decreaseswith time as the reaction progresses. As the reactant is consumed, there is less of it left to yet react. As less is left, less will react per unit (of) time, and that points to a reduced rate of reactant consumption. This leaves out any affects of end products or byproducts like, say, heat, and how the heat generated by a reaction would affect the rate of the reaction and, therefore, the rate of consumption of the reactants. Certainly heat is but one variable; there are other variables.

What happens to the reaction rate as a reactant gets gets used up?
The rate goes down.
How is the rate of reaction compared with the time the reaction is carried out?
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
Why the reaction mixture doesn't have 50 percents reactants and 50 percents products at equilibrium position?
Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Take this example:2NO2(g) ↔N2O4(g)At this point of the reaction the rate of N2O4 produced from NO2 is the same as the rate of NO2 produced from N2O4. The key aspect to keep in mind is that the amounts (of moles) of products and reactants at equilibrium is not always 50%/50%. It is usually not.Finding the amounts of products and reactants present during a reaction can be found using Q. Q is known as the reaction quotient. Q can be found like so:Q=[products]/[reactants]reaction quotient =concentrations of products (M) / concentrations of reactantsQ is used to find this ratio at a certain point in time during a reaction (not atequlilibrium)Most likely, you will be given Keq, the equilibrium constant, for a reaction. The value tells you the concentrations of products/reactants at equilibrium. Comparing Q and Keqwill tell you whether a reaction is at equilibrium.Not to get off topic, the answer is that equilibrium does not mean that the reaction mixture has 50% reactants and 50% products. Equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.
Why does forward reaction is decrease in rate as time increase?
This is because the reactants are being used up to make products. Unless you add more reactants to the solution, the rate at which products will be made will start to diminish until there is an equilibrium. At this point products will be converted to reactants and reactants will be converted to products and the equilibrium will not shift however the forward rxn and the reverse rxn will be occurring at the same rate
The reactant represents the starting materials in a chemical reaction?
Reactants are the starting materials of a reaction. Reactants combine to form the products.

What happens to the rate of reaction as the reaction progresses?
The rate decreases as reactants are used up.

What does the rate law used to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What happens to the reaction rate when a catalyst is used in a chemical reaction?
With a catalyst the reaction rate is higher.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
Which of the following is not true of a catalyst?
A catalyst is a material which make possible a chemical reaction, improve the rate of reaction, increases the yield of the reaction; a catalyst doesn't react with reactants/products.
Products and reactants are used and created at the same rate when a reaction is at this stage?
Dynamic equilibrium.
How is a reaction rate measured experimentally?
There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.
What does the rate law used to determine the rate of reaction?
