It depends on the reaction you're trying to affect. Caffeine affects certain reactions, as does alcohol and sleeping pills. Ice slows quite a number of reactions, and lowering the body temperature can certainly affect almost all bodily reactions, since the human body is an chemical/electrical organism. Your Thyroid gland produces a hormone that speeds reactions and a problem with your Thyroid gland will certainly cause problems that are quite diverse. Clinical depression can also slow reaction rate. Exercises speed many reactions and do it in a far more healthy way than do chemicals. To get a more specific answer, you'll need to ask a more specific question.
Increases reaction rate.
Surface area affect the reaction rate because the contact between finely divided particles is improved.
Increasing the concentraion the reaction rate increase.
It leads to more frequent collisions, which increase reaction rate.
a catalyst can affect the rate of a reaction. speeding it up.
Increasing the temperature the reaction rate increase.
Increasing the concentration of the reactants increases the rate of the reaction.
if gases are involved in the reaction.
Increases reaction rate.
Yes they do. THey do that because your nervous and your body's reaction is having your pulse go faster.
Yes.why
Surface area affect the reaction rate because the contact between finely divided particles is improved.
?
The rate increases
The more collisions the faster the rate.
Increasing the concentraion the reaction rate increase.
Generally increasing the temperature and concentration the reaction rate is higher.
