Catalysts

Do catalysts speed up both the forward and reverse reaction?

[lindsay lathrop 2C]

Yes, catalysts speed up both the forward and reverse reactions. This is why the catalyst does not effect the equilibrium composition even though it is changing the rate of the reaction.

[Peri Bingham 1G]

Since the catalysts increase the rates of the forward and reverse reactions equally, equilibrium composition is not changed but is just reached faster.

[Amanda Wu 2C]

Yes, catalysts increase the rates of the forward and reverse reactions. In turn, both the forward and reverse rate constants, k and k', increase but their ratio, k/k' which equals the equilibrium constant K, remains the same.

[Ya Gao]

Yes, because catalyst lowers the activation energy which works in both the forward and reverse reactions.

[Alejandra Rios 1L]

Yes, a catalyst works to lower activation energy, therefore this corresponds to the rate of both the forward and reverse reactions.

[MorganYun1H]

catalysts lower activation energy therefore the forward and reverse rate will both increase.

[Danny Elias Dis 1E]

Do catalysts always enter with the reactants of the first elementary step and end with the products in the last elementary step, or can it be the other way around?

Is there any case where there must be a catalyst for a reaction to occur?

[Karan Thaker 2L]

Important to note catalysts lower Ea, through altering and lowering the transition state of the reactants. They can affect orientation to idealize reactants' position for a reaction, or also weaken bonds of reactants to make them easier to break.

Is there any case where there must be a catalyst for a reaction to occur?

You can think about enzymes, which are considered catalysts, in biological scenarios where they are required for some reactions to occur.

[Dong Hyun Lee 4E]

Catalysts increasethe rate of reactions as they lower the activation energy required to pass the transition state.

[Samantha Toscano 2C]

Catalysts do speed up both of these reactions as they lower the activation energy.

[Sarah Hong 2K]

The addition of a catalyst speeds up both the forward and reverse rates of the reaction by lowering the activation energy of both forward and reverse reactions.

[Sophia Hartwell 1F]

Yes, because a catalyst acts to reduce activation energy, this pertains to the rate of both forward and reverse processes.

[Justin An 2L]

Yes, both the forward and reverse reactions are sped up because the activation energy is lowered

[Ashley Gonzalez Dis 2A]

Yes, catalysts decrease the height of the energy barrier so the amount of activation energy for both the forward and reverse reaction decreases, therefore the reaction speeds up in both directions, forward and reverse. The catalyst would have to work equally in both directions because of the law of conservation of energy.

[Eszter Kovacs 1A]

yes, since catalysts lower the energy barrier that needs to be reached by the reaction in order it for to happen.

[andreagutierrez 3K]

Catalysts do in fact speed up both forward and reverse reactions. Since they love to lower the activation energy.
