(c) Catalyst does not get involved in the reaction
(d) All the bracket
Answers
Answer:
Catalyst is any substance that increases the rate of a reaction without itself being consumed.
The most important properties of catalysts are:
1. A catalyst increases the speed of a reaction, and it also improves the yield of the intended product.
2. A catalyst actually takes part in the reaction even though it itself is not consumed or used up in the course of the reaction.
3. A catalyst makes the reaction faster by providing an alternative pathway with a lower activation energy.
4. A catalyst is reaction-specific. It may not be effective in another reaction even if the two reactions are of similar type.
5. In a reversible reaction, a catalyst accelerates both the forward and the reverse reactions. So, the inclusion of a catalyst does not alter the equilibrium constant of a reversible reaction.
6.A catalyst can accelerate the rate of reaction but it can't initiate the reaction thus donot alter the spontaneity or ΔG

of the reaction
