∙ 11y agoA chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.
as surface areas increases, the rate of the reaction increases

What are the 5 important factors that influence the rate of a chemical reaction?
Temperature Surface area/phase of reactants Concentration of reactants Presence of catalyst Activation energy of reaction
Why crushing is done for a reactant before a chemical reaction?
the surface area of the particles are incresed so that the chemical reaction takes place fastly. for example if u have a granular sugar or powdered sugar what will be solved in water fastly surely the powdered form . bcoz of crushing surface area increses ! [ ENGR RIZI NFC IET MULTAN]
What does grinding solid reactants into powder - do to the reactant particles?
The powdered form of a solid reactant has an aggregate surface area that is many times greater than the solid blockfrom which it came. This makes any reaction proceed faster and more efficiently, usually resulting in enhanced yield as well.
What three factors influence an area's temperature?
The incident radiation, reflectivity of the surface and ambient temperature are three factors.
How does an increase in surface area affect the rate of weathering?
If you do a chalk experiment, you will find out that increasing the surface area speeds the rate of weathering. The reaction/weathering will happen quicker. Most people are doing this in science. Your welcome

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.
How is the rate of a reaction affected by reactant surface area?
That there is a bigger area of a solid exposed, so there is a greater chance of collisions causing a reaction.
How does increasing the surface area of a solid reactant affect the energy of molecular collisions?
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
Is this sentence true inceasing the surface area of a reactant exposes more of it to the reaction taking place?
true
How does surface area affect the rate of reaction?
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased: More particles are exposed to the other reactant, there are more collisions, the rate of reaction increases.
Why does a reaction proceed faster when the reactants have greater surfaces area?
A greater the surface area will cause the reaction will proceed faster because there are more available sites where another reagent or catalyst can "attack" the reactant.
List five ways you could increase the rate of a chemical reaction?
1) Add a catalyst 2) Add heat 3) Stir 4) Mix 5) Surface area of the reactant
Why use reactant in the powdered form?
A lump of solid has a much lower surface area compared to a powdered catalyst. Since most chemical reactions that are catalysed by solid phase catalysts (heterogeneous catalysts) occur on the catalyst surface more surface area = faster reaction.
Why are catalysts spread out in a reaction?
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
