Is a catalyst required in small amounts?
yes it is required in small amounts. The lesser the catalyst, the better is its efficiency.
What is the effect of a catalyst on the required energy to achieve effective collisions?
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
What are small amounts of gravity called?
small amounts of gravity
Is chrome poisonous in very small amounts?
Chromium 6 is poisonous in very small amounts. Chromium 3 is not poisonous in small amounts. In fact, your body requires a small amount of chromium 3.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Is a catalyst required in small amounts?
yes it is required in small amounts. The lesser the catalyst, the better is its efficiency.
What is cactalyst?
A catalyst is a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.

Poison - the opposite to catalyst
What is the effect of a catalyst on the required energy to acheieve effective collisions?
A catalyst lowers the activation energy of a reaction.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
What is the effect of a catalyst on the required energy to achieve effective collisions?
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
What catalyst is effective in destruction of atmosphere ozone?
Halogen Radicals can be called as catalyst in ozone destruction. They speed up the depletion of the ozone gas.
What are small amounts of gravity called?
small amounts of gravity
Is copper sulphate the best catalyst between zinc and hydrochloric acid?
Is aqueous copper (2)sulphate an effective catalyst in the reaction between zinc and hydrochloric acid.
Why few drops of nitric acid are added to a solution of silver nitrate and distilled water?
to acidify it for chloride test. you would not use hydrochloric as it contains chloride and interferes with chloride test. It may also act as a catalyst for the chloride test too. as small amounts can act as a catalyst for ester formation in organic chemistry.
Why is ferric chloride only used in catalytic amounts?
Iron chloride is only used in catalyst amounts because it is highly reactive and will release hydrogen which is highly flammable.
Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
