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.
When giving the rate of a chemical reaction why would it be significant to know that the reaction rate is an average reaction rate?
Reaction rates are dependent on the concentration of reactants. As a reaction proceeds, the reactants are used up and thus their concentration is lowered. THis means that the maximum rate of reaction will be at or immediately after time zero, when the reaction is only just begun, and the minimum will be when one or more of the reactants' concentrations have reached zero. Thus, any rate stated for the reaction would only hold for a specific time in the reaction progress and cannot be extrapolated to cover all of that progress. So a mean rate of reaction must be used; this can tell a person, when combined with either the time of beginning, time of ending, or the initial concentrations, what any of the others were for the reaction in question. This is impossible to do if given a specific rate and the time it applied to; you cannot calculate any new information from just those two data.
What is the name given to a substances used in a chemical reaction?
A substance used in a chemical reaction can either be a reactant or catalyst. If it is undergoing the reaction, then it is a reactant. If it does not undergo the reaction and just changes the rate of reaction, then it is a catalyst.
Why do reaction rates slow as time goes on?
There are fewer reactants left to collide.
Why aren't enzymes used up during a reaction?
It is not used up as it is a substance that the reactants can stick to, so there are more successful collisions (collision theory), increasing the rate of reaction; as opposed to reacting with the reactants.
What happens to the reaction rate as the reactants get used up in the reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What happens to the rate of reaction as the reaction progresses?
The rate decreases as reactants are used up.
What happens to the reaction rate as the reactions get used up in a reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What happens to the reaction rate as the reactants get used up in a reaction?
The rate of a reaction begins to decreases as reactant are used up
What effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
TO INCrease the rate of a reaction why would you increase the concentration of the reactants?
For most reactions which involve liquids or gases, increasing the concentration of the reactants also increases the rate of reaction. This is because the number of effective collisions are also increased which speeds up the reaction.

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.
How does the amount of reactants account for the differences in the rate of reaction?
The more reactant, the faster the reaction The less reactant, the slower the reaction hope that clears it up for you

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.
