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.

Chalk reacts with hydrochloric acid when mixed Will pounding the chalk into powder increase the rate of reaction?
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
If A chemical reaction occurs and the substances increase in temperature Does this break the law of conservation of energy?
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?
what would most likely result in the greatest decrease in the rate of a chemical reaction
Which are the products and reactants of a chemical reaction most likely to have in common?
Input: reactants --> [ They react ] --> Output: products = what you get out of it
Which of the following is the most likely a sign that a chemical change has happened?
D.Two liquids are mixed at room temperature and a gas forms.
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.

What will most likely happened if an appropriate enzyme is added to 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.

Why does freezing temperature generally increase the rate of a chemical reaction?
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.
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.

Which change in the climate of a location would most likely cause the greatest increase in chemical weathering of local bedrock?
greater precipitation in the summer

Why is fizzing and foaming a physical and chemical change?
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).
