Which of the following is a character of catalyst?
Options
- AIt changes the position of equilibrium.
- BIt increases the rates of both forward and Backward reactions equally in reversible reaction.
- CIt affects the energies of reactants and products of the reaction.
- DIt increases the activation energy of reactants.
Correct answer
B. It increases the rates of both forward and Backward reactions equally in reversible reaction.
Step-by-step solution
Reactions can be sped up by the addition of a catalyst, including reversible reactions involving a final equilibrium state. Recall that for a reversible reaction, the equilibrium state is one in which the forward and reverse reaction rates are equal. In the presence of a catalyst, both the forward and reverse reaction rates will speed up equally, thereby allowing the system to reach equilibrium faster. However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the fina
