Describe the change in the rate of reaction when the enzyme concentration is increased?

The increase of enzyme concentration increase the rate of reaction. Given a fixed amount of substrates, it means that the substrates will be digested faster as there are more enzymes to do the work. Substrate concentration, temperature, and pH value of the surrounding where the enzymes work on also affects the rate.

∙ 13y agoThe rate(speed) of a reaction is directly related to the concentration of the enzyme. As the concentration of the enzyme increases, the speed of a reaction will increase. This is because the more concentrated the enzyme concentration, the more particles there are to collide and react. There will be a stronger concentration of enzyme to react with the substrate.

∙ 14y agoWhen the concentration of enzyme is increased, there are more enzymes available for the substrate to bond to. Because enzymes increase the rate of reaction, having more enzymes increases the rate of reaction into a certain point. At this point, there are more than enough enzyme molecules to accommodate all of the substrate molecules.

∙ 13y agoIf there is more enzyme, then there is more enzyme to bind at the active site, so it will be faster. If the concentration was weaker there would be less enzyme and a less faster reaction.
If the solution is diluted with an inhibitor, this will also decrease the rate of reaction.

∙ 11y agoThe substrate concentration will have a positive correlation with the speed of enzymatic reaction, but only until a certain point/concentration, at which the speed of enzymatic reaction stays constant.
The reason for this is enzymes are very productive and optimized for their job, and are able to work on several molecules (one after another) and change their shape, or in other words, turn them into a different molecule. When you begin with a small amount of enzymes, it will take relatively longer for the enzymes to react with all of the substrate, as opposed to when there are more enzymes present to work on the substrates. The point at which the speed stays constant is when there are equal number of enzymes to substrate, at which the extra enzymes do nothing and are not needed for the operation.

What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
How does the rate law show how concentration changes change the rate of reaction?
as concentration increase the faster the rate of reaction and vice versa
Describe the factors which affect chemical reaction rates?
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
What would increase the concentration of reactants?
It means that there will be more particles of the reactants in the vessel, so they are more crowded and collisions of the right energy are more likely. or collisions of the right energy are more likely.

What are two variables that would cause a chemical reaction to have a fast reaction rate?
Increased concentration, increased temperature, and a catalyst will all increase reaction rates relative to what they normally are. Some reactions however will still be slow even with the change in these variables.

How is the effect on concentration change on the reaction rate seen in the rate law?
The exponents determine how much concentration changes affect the reaction rate

How does the percentage of ionization change with its concentration?
The percent ionization of a weak electrolyte upon dilution is increased. This is in accordance with Le Chatelier's principle. Dilution causes the reaction to shift in the direction of the larger number of particles to counter the effect of the decreasing concentration.
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.
3 conditions that will influence the direction a reaction will go?
change in concentration change in temperature change in pressure
What changes the rate of a reaction?
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.
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.
