In a reversible reaction the catalyst reduces the time to reach equilibrium by:
- A
Increasing the rate of forward reaction
- B
Decreasing the rate of reverse reaction
- C
Increasing the rate of both forward and reverse reactions
- D
Decreasing the rate of both forward and reverse reaction
Option c is correct because a catalyst in a reversible reaction speeds up both the forward and reverse reactions equally. It does not change the position of equilibrium but helps the system reach equilibrium faster by reducing the time needed for the reactions to proceed in both directions.
A catalyst can increase the rate of the forward reaction, but it does not affect the rate of the reverse reaction.
A catalyst does not specifically decrease the rate of the reverse reaction.
This is correct because a catalyst in a reversible reaction speeds up both the forward and reverse reactions equally. It does not change the position of equilibrium but helps the system reach equilibrium faster by reducing the time needed for the reactions to proceed in both directions.
A catalyst does not decrease the rate of both forward and reverse reactions.
