What are three methods to speed up a chemical reaction?

Answer 1

* breaking a solid into something smaller (to increase its surface area) * make the solution more concentrated, * increase the temperature. Other methods for increasing the rate of reaction are incrasing the pressure and adding a catalyst.

Answer 2

Three methods you could use to speed up a chemical reaction are:

1. The addition of a catalyst, the catalyst would speed up the reaction without being used up.

2. Increase the surface area of the reacting elements, more surface area equals more room to react.

3. Increasing the temperature. In general, increasing the temperature of a reaction will speed it up. This is because the molecules will be moving faster.

Answer 3

Factors which speed up a chemical reaction are:

1. Increased temperature, because the particles move faster and therefore collide more often.

2. Increased concentration of a solution, because the particles are more crowded and therefore collide more often.

3. Increased pressure of a gas, for the same reason as point 2.

4. The presence of a catalyst, which works by lowering the activation energy of the reaction.

5. Increasing the surface area of a solid by breaking it into smaller pieces, which brings more reactant into contact with the liquid reactants.

Answer 4

1) Concentration.

2) Temperature.

3) Surface area of the reactant.

4) Catalyst.

5) Nature of the reactant.

Answer 5

-the amount or concentration of reactants

-temperature

-a larger surface area

-catalysts (helper chemicals)

Answer 6

1.Catalyst

2.Heating/byincreasing temperature

3.by increasing concentraion

Answer 7

Generally, increasing the temperature, stirring and increasing the concentration of reactants will increase the speed of a chemical reaction, but not always.

Answer 8

- increasing the temperature
- increasing the concentration
- increasing the pressure

Answer 9

You can heat it.You can add a catalyst.

You can agitate it.

Answer 10

Heat and a catalyst.
