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]
Why is the rate of reaction increased when magnesium is powdered rather than in solid form?
The rate of reaction increases when magnesium is in powdered form because it has a larger surface area compared to solid form. This increased surface area allows for more collisions between magnesium atoms and reactant particles, leading to a higher reaction rate.
What are the 5 important factors that influence the rate of a chemical reaction?
The key factors that influence the rate of a chemical reaction are concentration of reactants, temperature, presence of a catalyst, surface area of reactants, and the nature of the reactants and products.
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 affects how quickly acids react with calcium carbonate?
It's the concentration of the acid.Limestone and marble are forms of calcium carbonate.Acid rain reacts with calcium carbonate. The stronger the acid the more quickly it effects calcium carbonate and dissolves.
Why does surface of a reactant influence the rate of the reaction?
A 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.

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 a reactant surface area?
Reactant surface area refers to the total area of a substance available for chemical reactions to occur. It plays a crucial role in determining the rate of a chemical reaction as it affects the frequency of collisions between reactant molecules. Increasing the surface area typically leads to a faster reaction rate as it provides more contact points for particles to interact.
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 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.
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 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 .

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.
