What factor in reaction rate is related to the amount of reactants?
This is the concentration of reactants.
Why don't the amount of reactants and products change in a reversible reaction?
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
In a reverse reactionproducts are formed from reactants and reactants are formed from products When they yield the same amount?
Of material. They will need to have the same amount of atoms present for this process to work out correctly.
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
What is the term for The amount of a solute per amount of solvent?
The term for "the amount of solute dissolved in a given volume of solution" is "concentration"
What factor in reaction rate is related to the amount of reactants?
This is the concentration of reactants.
What happens to the mass of reactants in a chemical reaction?
The reactants will form products, so the amount of reactants will decrease, proportionally to the increase in products. The amount can be expressed in mass, concentration or moles.

What are the two factors that affect the amount of voltage produced by a chemical cell?
The electrochemical cell develops voltage based on a difference in the internal half cell potential. Each half cells produces a chemical reaction which in turn produces a voltage that is affected by the concentration of reactants as well as the type of reactants within each.
What is meant by a stress on a reaction at equilibrium?
A change in the amount (or concentration) of at least one of the reactants and products or a change in temperature or pressure.
What factors can influence the rate of reaction?
Concentration of reactants and time; also: temperature, pressure, stirring, added catalyst, the type of solvent, surface area of reactants, effect of other physical factors as irradiation, etc.
What is is an yield?
The amount of product which should be produced from a given amount of reactants where one of the reactants is a limiting reagent.
Relationship between the concentration of reactants and the total number of collisions?
For any chemical reaction, there is a theoretical yield for the products. The theoretical yield is based on the balanced equation for that reaction. If any of the reactants is present at a lower amount, then your actual yield will be less than the theoretical yield.
When a solution is?
when no more solute will dissolve ========== when the concentration of the solute is equal to the concentration that would be in equilibrium with any solid of the same substance - when that happens, no more solute will dissolve, or more precisely, if any more dissolves, it would be expected to cause the same amount to precipitate out, thus keeping the concentration constant.
What is a precipitate and when is it observed?
an insoluble sold formed in a chemical reaction that is taking place on a solution. Observed when the amount (concentration) of that substance is greater than its solubility. small crystals settel out in the container.
When a solution is saturated?
when no more solute will dissolve ========== when the concentration of the solute is equal to the concentration that would be in equilibrium with any solid of the same substance - when that happens, no more solute will dissolve, or more precisely, if any more dissolves, it would be expected to cause the same amount to precipitate out, thus keeping the concentration constant.
