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.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
How could you speed up the reaction of limescale and descaler?
concentration,catalyst, temperature and surface area effect
How do you increase the rate of a reaction of a solid?
Grinding the solid into a powder increases the surface area and increases the rate of the reaction. Heating it would also increase the rate.
Why does crushing a solid increase the speed at which the solid dissolves?
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
How do you alter the reaction rate of a chemical change?
Heat - increases it Increased stirring - increases it larger surface area - increases it catalyst - usually increases it and the reverse of the above slows the reaction down

What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
What effects the rate of a chemical reaction?
Temperature, pressure, catalyst, surface area
Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
What factors change the rate of chemical reaction?
Adding a catalyst to the process will make the chemical reaction go faster. Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.
What is the relationship between surface area and rate of reaction?
The increase in surface area of reactants increases the contact between reacting molecules, atoms or ions so the rate of reaction becomes increased.
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 could you speed up the reaction of limescale and descaler?
concentration,catalyst, temperature and surface area effect
Why does surface area of a reactant influence the rate of the of the reaction?
by pooing on the leg
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.
