I'm not sure exactly. Essentially, a chemical reaction is the result of collisions between molecules. If the collision is strong enough, it can break the chemical bonds in the reactants, resulting in a rearrangement of the atoms to form products. The more MOLECULES included, will speed up the reaction, so, the less used, means it should go slower. That's one.
Another is heat. Heat is a way of causing a collision to speed, so, again, going opposite, if you COOL the chemicals, they should react slower.
The third would be to "Block" the chemicals from eachother. This, is linked to the first one. They will have to "find a way" through the object, in order to react, this will be a slow process, meaning less Molecules are colliding, slowing the reaction.

- Decreasing the temperature: Lowering the temperature reduces the kinetic energy of the molecules, slowing down their movement and consequently the frequency of collisions.
- Decreasing the concentration of reactants: Lowering the concentration of reactant molecules decreases the chances of successful collisions.
- Adding an inhibitor: Inhibitors are substances that disrupt the reaction process, slowing it down by interfering with the reaction pathway.
- Changing the pressure: For reactions involving gases, changing the pressure can alter the equilibrium and slow down the reaction rate.
This depends on the chemical reaction taking place. Decreasing surface area of the reactants will slow a reaction. Depending on how concentrated the reactants are the reaction will also be changed. (low concentration of reactants slower rate of reaction). Altering the temperature (usually by lowering the temperature - but not always) will alter the rate of the chemical reaction. Agitation (shaking or stirring or the reactants) typically increases the rate of the chemical reaction. The input of external energy into the chemical reaction, whether it be light, heat, or electrical current will increase the rate of the reaction, that is, if the reaction is nonspontaneous to begin with. If a catalyst is present, it will lower the activation energy and thus increase the rate of the reaction. A decrease in pressure will slow down the reaction.

What are the four occurrences indicate a chemical reaction has occurred?
A chemical reaction can result in any or all of the following: - a change in temperature (up or down) - a change in color - a smell that wasn't there before - the formation of bubbles (indicating the production of a gas) - the formation of a precipitate
What are the four sides of fire quadrangle?
The "four sides of the fire quadrangle" refer to the four components necessary for a fire to occur: fuel, oxygen, heat, and a chemical chain reaction. Without any one of these elements, a fire cannot be sustained.
What are the four clues to a chemical reaction?
The four clues to a chemical reaction are: formation of a gas, formation of a precipitate, change in color, and release or absorption of energy (heat or light).
Each of the four types of reaction stoichiometry problems requires using a?
balanced chemical equation in order to relate the quantities of reactants and products involved in the reaction.
Four elements that must be present for fire to exist include?
For a fire to exist, four elements must be present: fuel, heat, oxygen, and a chemical reaction. The fuel provides the material to burn, heat is needed to increase the fuel's temperature to its ignition point, oxygen is required for the combustion process, and a chemical reaction occurs between the fuel and oxygen to sustain the fire.

What are the four components of fire?
the four components of fire are heat, fuel, oxygen and the sustaining chemical reaction
What are the four possible outcomes of mixing two chemicals in solution?
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction
What are four ways you can detect chemical reaction?
Precipitation formsProduction of bubblesTemperature changeColor change
What four factors affect how rapidly chemical reaction takes place?
Four factors are:- temperature- pressure- catalysts- stirring

What are four different types of chemical weathering?
The four different types of chemical weathering are hydration, oxidation, carbonic acid action and hydrolysis. Chemical weathering is a chemical reaction that erodes certain things such as building materials and rocks.

The four clues to a chemical reaction are: formation of a gas, formation of a precipitate, change in color, and release or absorption of energy (heat or light).
Is the formation of gravity a chemical reaction?
No. Gravity is one of the four fundamental forces, and has nothing to do with chemistry.
Each of the four types of reaction stoichiometry problems requires using a?
balanced chemical equation in order to relate the quantities of reactants and products involved in the reaction.
Is the formation of magnetism a chemical reaction?
No. Magnetism is one of the four fundamental forces and has very little to do with chemistry.
Why carbon cannot lose or gain its electron?
It is not that way. Carbon gains electrons while a chemical reaction to have 8 shells in the outermost orbit. Though it has 4 electrons in the outermost orbit, it usually gains four electrons or shares four electrons while a chemical reaction. eg hydrocarbons methane butane propane.
