changing the temperature, concentration of solutions, light intensity, having the presence of a catalyst or altering the surface area of solid particles. I think that's it.
Change the temperature.

There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
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. ~HellsBaran Any questions please EMail me at: Vistekis@yahoo.com.

There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.

There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
1. Increase the temp 2. Increase surface area 3. Increase the pressure of the system
The reaction rate is dependet on temperature, pressure and reactants concentration.

Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.

A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
The 2 ways to increase chemical reaction rate are applying heat or a catalyst. So it is A : Applying heat. ;)
don't know
There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.
