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.

Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
What is meant by the rate of reaction?
The how much speed it takes for two substances to make one product. Many factors can affect this including the temperature, the surface area, the concentration, the catalyst and the pressure (only applies for gases)
How does surface area affect the rate of cooling?
the color of an object will affect the rate of cooling e.g black objects cool down faster than shiny objects, the temperature around the object will also affect the rate of cooling, if the surrounding is cold, a hot object will cool faster than when the surrounding is hot.
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.
Why does stirring affect diffusion?
Stirring decreases the time it takes for a substrate to dissolve in a solvent. More of the substrate is exposed to the solvent, thus, allowing it to dissolve quicker. This is similar to why increasing surface area during a chemical reaction, increases the rate of the reaction.
Where surface area is not affect the rate of a reaction?
Surface area affect the reaction rate because the contact between finely divided particles is improved.
What do concentration surface area and temperature have in common?
They can all affect the rate of 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.
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
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.
How does the surface area of a rock affect the rate of weathering.?
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
How does the surface affect the rate of weathering?
more surface area= faster rate of weathering
How does the area affect the rate of reaction?
by pooing on the leg
What factor does affect the most rate of reaction?
Factors affecting the rate of reaction 1. Temperature 2. Catalyst 3. Concentrations of the reactants 4. Nature of the reactants 5. Surface area of the reactants
How does surface areas affect the rate of weather?
more surface area= faster rate of weathering
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.
How is surface area related to area?
How does slope affect the rate of weathering
