Which one is not true about catalyst ?a)The catalyst is unchanged at the end of the reactionb)A small quantity of catalyst is often sufficient to bring about considerable amount of reactionc)The catalyst accelerates the reactiond)In a reversible recation the catalyst alters the equilibrium positionCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

The correct answer is Option D.

The catalyst is unchanged chemically at the end of a reaction. During the reaction between the chemical intermediates and the reactants, the catalyst is regenerated.
The catalyst accelerated the reaction. A catalyst is a substance which speeds up a reaction but is chemically unchanged at the end of the reaction.
In a reversible reaction, the catalyst does not alter the equilibrium position but increases the rate by decreasing activation energy and temperature.
A small amount of catalyst is often sufficient to bring about a large change in reaction. Catalytic action is a chemical reaction between the catalyst and a reactant, forming chemical intermediates that are able to react more readily with each other or with another reactant to form the desired end product.

Answer

In a reversible reaction the catalyst wouldn't alter equilibrium position, it will only increase rate of reaction because of which equilibrium position will be attained  soon... So option (d) is correct...

Answer

In any process the catalyst wouldn't alter the rate thus the equilibrium position. it would just speed up the reaction. thus, op D .
