Catalyst
Can someone please explain why adding a catalyst increases the reverse reaction? I thought that it would decrease when looking at the graph, but I'm just reading it wrong.

Re: Catalyst
It increases the speed of both reactions because it lowers the activation energy. Therefore the reverse reaction would also have a lower activation energy and therefore take place at a faster speed.

Re: Catalyst
Going off of this, will the catalyst have the same effect on both the forward and reverse reactions? In other words, is the increase in speed because of the catalyst the same for both reactions? Thanks!

Re: Catalyst
catalysts increase the speed of the reaction rate but decrease the activation energy. This holds true for both the forward and reverse

yes I believe the increase in speed is the same for both the forward and reverse reactions

Re: Catalyst
It is changing the pathway for both the forward and reverse reaction by lowing the activation energy, increasing the speed of both
Re: Catalyst
It increases the speed of both forward and reverse pathways of the reaction by lowering the activation energy.

Re: Catalyst
The forward and reverse reactions follow the same energy pathway except in reverse, so when a catalyst lowers the activation energy for a reaction is makes it so both the forward and reverse reactions need less energy to proceed, meaning they will both go faster.

Re: Catalyst
The activation energy for both forward and reverse processes will be lowered when a catalyst is introduced. Thus the rates to convert back to each whether it be from reactant to product or product to reactant will be faster since less energy is needed for the reaction to completely take place.

Re: Catalyst
If it lowers the EA of the forward it must lower the reverse too because think about it of the reaction profile. They share the Ea hump in a sense. So if it goes down it helps both ways of the reaction.

Re: Catalyst
Adding a catalyst will lower the activation energy, which both the forward and reverse reactions need to overcome. So, when the Ea is reduced as a result of the addition of a catalyst, then the forward and reverse reactions will both be overcoming a smaller value of Ea.

Re: Catalyst
Adding a catalyst results in a decrease in activation energy in a reaction, which means that it goes faster! This is true for the reverse reaction too, so it goes faster as well :)

Re: Catalyst
To add on, when a catalyst is added, the overall K value stays the same since the forward and reverse rates are equal.

Re: Catalyst
Catalysts lower the activation energy, but increase the speed of the reaction rate. Same thing goes for both forward and reverse rxns.

Re: Catalyst
I find that the best way to think about this is to visualize a reaction profile. If you add a catalyst, the activation energy (the bump on a reaction profile) will go down. This means that for both the forward and the reverse reaction, there is less energy required to get to the end result. This is why the catalyst speeds up both the forward and the reverse reactions. In addition, a catalyst will not change K and as such, both the forward and reverse reactions need to be sped up.

Re: Catalyst
A catalyst increases the speed and lowers the activation energy of the forward and reverse reaction. Hope this helps!

Re: Catalyst
Since the activation energy of the reaction is lowered by the catalyst, it acts to increase the speed of both the forward and the reverse reaction. If you look at the graph, the bump at the transition state is a little lower due to the catalyst.

Re: Catalyst
by lowering the activation energy it increases the speed of both forward and reverse pathways of the reaction

Re: Catalyst
A catalyst lowers the activation energy, which results in the rate of forward and reverse reactions to increase.

Re: Catalyst
A catalyst lowers the activation energy (the minimum amount of energy that a species must have in order to react), therefore it speeds up the time that it takes both the forward and reverse reaction to happen. Hope this helps!

Re: Catalyst
A catalyst decreases the activation energy and increases the reaction rate for the reaction going both ways.

Catalysts lower the activation energy for both the forward and reverse reaction. As a result, both rates are increased.

Re: Catalyst
The catalyst will cause the activation energy to be lowered, which will increase the reaction rates.
