Which is a characteristic of a catalyst?
Open in App
Solution
The correct option is B It alters the rate of reaction
Some properties of catalysts are:
1. A catalyst improves the speed of a
reaction.
2. A catalyst takes part in the reaction
even though it will not be consumed or used up in the course of the reaction.
3. A catalyst makes the reaction faster by
giving an alternative path with lower activation energy.
4. In a reversible reaction, a catalyst
accelerates the reaction in both directions. Therefore, the inclusion of a
catalyst will not change the equilibrium point.
Thus the only the third statement is true.
The correct option is C.
