A smaller particle size means a larger surface area, which in turn, means that more of that substance is exposed to the other reactant(s). This facilitates more collisions which means a faster reaction will happen. Dissolving a substance in water is the ultimate way to decrease particle size/increase surface area which is why many reactions are carried out in solution because outside solution they would take forever.

∙ 15y agoThe reaction can occur on more surface area of the reactant. Eg. If you have a solid dough ball and bake it, the inside takes a while to heat, whereas if you have a load of small bits it goes quite quickly. A bit abstract of an example but however.

By decreasing this you can speed up a chemical reaction?
Decrease the activation energy to speed up a chemical reaction.
When heat is increased does the chemical reaction speed up?
The effect of heat on a chemical reaction will depend on whether the chemical reaction is exothermic (producing heat), or endothermic (requiring an input of heat). If the reaction is endothermic, then adding heat will increase the speed, but the opposite is true for an exothermic reaction.
How does pressure speed up a chemical reaction?
Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves solids or liquids has no effect on the rate of reaction.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
What increases the reaction rate by increasing particle speed?
An increase in temperature will increase the speed of the particles and cause the particles to both bump into one another more frequently and with more energy thus increasing the reaction rate.
By decreasing this you can speed up a chemical reaction?
Decrease the activation energy to speed up a chemical reaction.
Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.
What is the speed at which new particles form in a chemical reaction?
13,450mph Source chemisty
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
How is the speed of chemical reaction related to the spontaneity of the reaction?
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
What can a chemical reaction be speeded up by?
A catalyst can speed up a chemical reaction.
The speed at which new particles form is called?
The speed of which new particles form is called the rate of reaction.
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
What function catalyst perform in chemical reaction?
Catalysts speed up the chemical reaction.
Adding a catalyst increases reaction speed by?
Catalysts lower the activation energy required for a chemical reaction. Activation energy refers to the mininum amount of energy that the reactant particles must possess so that effective collisions between them (hence a chemical reaction) can occur.
