That would depend highly on the type of chemical reaction. Usually increasing the speed of the molecules by heating, stirring, etc has some effect. However, not all reactions are benefited by this. An example is the formation of carbonic acid. A solution of weak carbonic acid is formed by dissolving carbon dioxide gas in water. Warmer water is incapable of dissolving as much carbon dioxide as cold water and stirring/agitating the water only speeds up the loss of carbon dioxide.
Increasing the concentration of reactants usually has good effect, but can be dangerous.
Be sure of any reaction BEFORE preforming it.

Chemical weathering will occur most rapidly when rocks are exposed to the?
Chemical weathering happens quickly in environments with warm temperatures, lot's of rainfall, and lush vegetation. These conditions produce thick soils that are rich in organic matter. When the carbon dioxide formed from the organic matter mixes with rainwater, it forms carbonic acid, which is a big factor in chemical weathering. In which could take place in tropical rainforests.
What are the most common evidences of chemical reactions?
Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
Is helium inflammable?
No it isn't. Helium is the most perfectly inert of all the elements. It does not undergo chemical reactions of any kind, under any circumstances.
How does an increase in surface area affect the rate of weathering?
If you do a chalk experiment, you will find out that increasing the surface area speeds the rate of weathering. The reaction/weathering will happen quicker. Most people are doing this in science. Your welcome
What initiates chemical reactions by breaking bonds in the reactants?
That process is called a chemical reaction.
Why is water important in the cells in your body explain with chemical reactions?
It speeds up the chemical reactions so most reactions wouldn't happen without water.
What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
Does chemical reactions need water?
Yes, most chemical reactions involved in metabolism do require water.
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
Where in a cell do most chemical reactions take place?
Most chemical reactions take place in the cytoplasm.
What chemical reactions are most common to break down the molecules?
These are decomposition reactions.
What are the chemical reactions with hydrogen?
Hydrogen undergoes innumerable chemical reactions. Here is the most familiar: 2H2 + O2 = 2H2O
In what inorganic compound do most chemicals reactions occur?
The most chemical reactions occur in water solutions.
How does increasing temperature increases rate reaction?
Temperature can increase and decrease the rate of reactions. Heat increases, while cold decreases the rate of reaction. With the help of enzymes.
Speeds up chemical reactions in the cell?
enzymes help reduce the requirement for reactions to take place within the cell. have a look http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Enzymes.html enzymes help reduce the requirement for reactions to take place within the cell. have a look http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Enzymes.html
What do most of the chemical reactions involved in metabolismrequire?
air
Most chemical reactions within cells could not take place without?
Most chemical reactions within cells could not take place without water
