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 is lactulose in a liquid form?
It is because of the process they use to manufacture it. However, you can get lactulose in a powdered form. I believe is is called Kristalose.
In the chemical reaction in which sucrose is heated and decompose to form carbon dioxide and water is a reactant?
Yes, sucrose is the reactant.
Do enzymes form a permanent or temporary association with a reactant?
temporary
Why are some sodium thiosulphate powdered before being used?
Dissolution of any material is faster in powdered form.
What happen if more product is added to a system at equilibrium?
more reactants will form
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 is powdered metalurgy?
Powdered metallurgy is the process of mixing elements in powdered form and compacting them. The compacted form is then heated to form different shapes of metals.
Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.
Is hydrogen the product or reactant in H2O?
The reactant, because it is reacting to form the product of H2O.

When two substances react to form products the reactant which is used up is called the .?
limiting reactant

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]
In the chemical reaction in which sucrose is heated and decompose to form carbon dioxide and water is a reactant?
Yes, sucrose is the reactant.
In the chemical reaction in which sucrose is heated and decomposes to form carbon dioxide and water is a reactant?
Yes, sucrose is the reactant.
What is an element or compound that enters into a chemical reaction?
A reactant or reactants enters into a chemical reaction to form product(s)
How do you determine a mineral’s streak?
The color of a mineral in powdered form is called the mineral's Streak
