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 rough surface of a catalyst is more effective?
Rough surfaces form irregular surface increase the surface area. Catalytic action is directly proportional to the area of contact.
How many moles of precatalyst H2ptcl6 are used in this reaction?
The number of moles of catalyst depends on the reaction under consideration. Compared to the substrate, about 10-2 to 10-6 times of the catalyst can be used. The lower the amount of the catalyst, the more effective it is.
Why are powdered substance more effective adsorbents than their crystalline forms?
powdered substances have more surface area so they can be broken down quicker than substances with less surface area and that will cause the sustance to be absorbed quicker.
What do parties in government form to have enough votes to be effective?
Coalitions. They form coalitions together to try and make them more effective.
What is the main ingredient of Hi C drink?
Either water or sugar, more likely water if its not in powdered form.
What does a catalyst do in washing powder?
because catalyst is more concentrated chemical
Which form of glucose is more effective solid or liquid and why?
wertyu
Why is the rate of reaction increased when magnesium is powdered rather than in solid form?
Because more surface area is exposed.
Is white sugar the same as granulated sugar?
no because white sugar is more clumped than powdered sugar and powdered sugar doesn't taste like sugar that much Powdered sugar is chemically not fundamentally different from regular sugar, just more finely ground. However, powdered sugar may contain additives to prevent clumping. you are exactly right!!!! by Terrier23
What is the function of anhydrous zinc chloride in the formation of fluorescein?
Zinc Chloride catalyses the reaction of e.g. phatalic anhydride and resorcinol. If you head these three as powdered substances with a bunsenburner, they react much faster. After solving this mixture in water, you can filtrate the Zinc Cholride out of the solution. For more examples what a catalyst does, read Wiki or Google catalyst. Good Luck
Why catalyst does no react with the reactants?
A catalyst is something that speeds up the reaction by providing a more suitable environment for it to occur, but is itself not consumed in the reaction. The simplest answer would be that if it reacted, then by definition, it would be another reactant and no longer considered only a catalyst. The reason the catalyst is not affected can vary, but it could be because it's already in a stable form, stable enough not to be affected with the reactants.
