Which one is not true about catalyst ?a)The catalyst is unchanged at t...
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.

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...

Similar Class 12 Doubts

A cyclotron is a kind of particle accelerator invented by Ernest O. Lawrence at the University of California, Berkeley, in 1929–1930, and patented in 1932. A cyclotron accelerates charged particles along a spiral path outward from the center. The particles are guided by a static magnetic field to a spiral trajectory, and accelerated by a rapidly changing electric field (radio frequency). For this invention Lawrence received the 1939 Nobel Prize in Physics.Cyclotrons were the most efficient particle accelerator equipment until the 1950s, when the synchrotron replaced them, and are now used in science and nuclear medicine to generate particle beams.This will toss the particle out of resonance with the oscillating field which means that when the particle reaches the hole between the dees, the extremity of the dees won't change. Thus, the particle won't be accelerated further.So, Cyclotron isn't reasonable for accelerating electrons. Because of the small mass, the speed of electrons increments quickly. Similarly, because of fast relativistic variation in their mass, the electrons escape step with the oscillating electric field.Hence, option A is the correct option.
