What determines how fast a reaction happens?

Kinetics


Rate of reactions?

The rate of a reaction is the time it takes for a reaction to take place. The rate of reactions can be affect by different factors such as the temperature, the air pressure, the concentration of each substance and whether a catalyst is used (a catalyst is something that lowers something's activation energy so the reactants have more energy to react). A reaction happens when atoms collide with each with a big enough force therefore a bigger surface area would help speed this up. Also the amount of energy the particle/atoms have helps. With these factors you can determine the speed at which a reation happens. Any questions?


What the difference between reaction and response?

A reaction is what happens to the body when a stimulus is applied, a response is what happens next; i.e a stimulus illicits a reaction which illicits a respose. For example, glucose in the blood (a stimulus) causes the pancreas to release insulin (a reaction), which in turn causes the cells to take up glucose from the blood (a response).


What happens to the rate constant of a chemical reaction when the temperature increases?

Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.


What happens to an enzyme after a biochemical reaction?

After a biochemical reaction, an enzyme typically remains unchanged and can be reused in other reactions.

What happens when you try to fly?

well your start off point and how high it is will generally determine whether you live or die. the higher up it is the less likey your chance of survival is.
