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 factors
etc.
Most chemical reactions will happen faster at higher temperatures.
For most reactions, the raising of the temperature of the reactants.
increasing temperature
decreasing a reactant's concentration
increasing temperature
Yes because make the chalk into a powder increases its surface area so it is more likely to react, so rate of reaction is increased
no, the energy came from an external source most likely.
what would most likely result in the greatest decrease in the rate of a chemical reaction
Input: reactants --> [ They react ] --> Output: products = what you get out of it
D.Two liquids are mixed at room temperature and a gas forms.
This is a chemical reaction.

The enzyme will act as a catalyst, a compound that lowers that activation energy of the reaction, and therefore, increase the rate of the reaction.
no, the energy came from an external source most likely.

Consider kinetic theory. Since heat is the rapid movement of particles, the more temperature there is, the more movement. If the particcles in a chemical reaction are moving constantly, they are much more likely to collide and react with one another.
D.Two liquids are mixed at room temperature and a gas forms.
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.

When something fizzes and foams, it's producing some sort of gas within it, thus it's going from a solid/liquid to a gas (a physical change). But, this gas is likely not the same material that it came from. it's just a byproduct of a chemical reaction with in it (a chemical change).
