Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
What does a catalyst not do?
Catalysts do not change the postition of the reaction's equilibrium. Adding a catalyst will increase the rate of reaction, but it will do this by providing another pathway for the reaction to occur acros, meaning a lower activation enthalpy is needed. :)
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
What is the substance that alters the rate of a chemical reaction without being permanently changed in the reaction?
These are called catalysts.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
When does chemical equilibrium occur?
When reactants and the products that are also contributing to a chemical reaction show no sign over change over time, chemical equilibrium has taken place. Chemical equilibrium can be called a "steady state reaction". It must be noted, however, that just because nothing has changed, it doesn't necessarily indicate that the interaction has stopped.
Why is a chemical reaction called a chemical reaction?
Because this reaction involve chemical compounds as reactants and products and the chemical structure and composition being changed.
Why is the boiling of water a physical reaction and not a chemical reaction?
During boiling the chemical composition is not changed.
A compound can only be changed how?
A compound can only be changed by a chemical reaction.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
Is sawing a log chemical reaction?
No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.
What makes a chemical reaction?
to see if a chemical has changed look out for bubbling and or fizzing
What change could happen during a chemical reaction?
the chemical shall be changed
According to the law of conservation of matter the number of is not changed by a chemical reaction.?
According to the law of conservation of matter, the total mass of substances before a chemical reaction is equal to the total mass after the reaction. This means that the number of atoms is not changed during a chemical reaction, only their arrangement.
In a chemical reaction what subatomic particles are being changed?
the electron
Is it true In a chemical reaction reactants are changed into products?
True
