Increasing the surface area of one of the reactants, increases the rate of reaction as there is more of the reactants available to react, e.g. a fine sodium powder will react faster than a block of it. you wouldn't put a whole potato into a deep fat frier to cook chips, you'd cut it up smaller so it cooks faster. .

∙ 13y agowell i guess its because the rates are different

∙ 13y agoYes, it is one of the four measures to speed up a reaction when solids are involved.
(Others are: higher concentration or pressure, heat it up, and add an enzyme ore catalyst)

What is the effect of cutting one single strip of magnesium into more than one when doing a chemical reaction?
The surface area of the magnesium is increased. The reaction will be larger, but normally will take less time.
What does not increase the number of particles of a substance available to react in a chemical reaction?
increasing the surface area
What speeds up in chemical reaction?
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.
How does the surface area affect the rate of a reaction?
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
What are three things that will slow-down the rate of a chemical reaction?
There are three things that can slow down a chemical reaction. You can have an inhibitor, something that is used to decrease the rate of a reaction, you can decrease the temp. making it colder, and decreasing the surface area (it takes longer for something to dissolve like a whole sugar cube, when it takes only a matter or seconds for a spoon full of sugar to dissolve). Hope that helped! If you need any more help, just comment.
What do concentration surface area and temperature have in common?
They can all affect the rate of 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 effect of reactant surface area on the reaction rate?
surface area has simple constant factor with the rate of reaction. Rate = (surface area)[concentrations with coefficients] the greater the surface area the greater the rate of reaction in a simple constant multiple.
What is the effect of cutting one single strip of magnesium into more than one when doing a chemical reaction?
The surface area of the magnesium is increased. The reaction will be larger, but normally will take less time.
What effects the rate of a chemical reaction?
Temperature, pressure, catalyst, surface area
What will increase a chemical reaction?
-Temperature ^ -More surface Area -More particles -Catalysts
What will increase chemical reaction?
-Temperature ^ -More surface Area -More particles -Catalysts
Does the size of the reactants affaect the speed of a chemical reaction?
Yes. The more surface area that is exposed, the greater the speed of the reaction.
Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
Is it true that the mechanical breakdown of food exposes a larger surface area for chemical digestion?
Yes, it is true. The reaction rate depends also on the surface area of the reactants.
How could you speed up the reaction of limescale and descaler?
concentration,catalyst, temperature and surface area effect
Why is powder in a chemical reaction used instead of lumps?
Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.
