Catalysts reduce the activation energy between reactants to products, meaning it takes less energy to make the forward reaction occur

Catalysts work by giving an entirely new pathway for the reaction to occur with a lower activation energy. Therefore, the curve would be lower.

A catalyst brings down the activation energy, effectively increasing the speed at which the reaction occurs. Graphically this would bring down the very top peak on the graph as the activation energy is lowered to make the reaction occur. Hope this helps.

A catalyst would lower the peak on a curve since it can speed up the rate of a chemical reaction by providing a faster route.

Catalysts lower activation energy which speeds up rxn.

A lower peak would be seen with a catalyst.

Catalysts lower the activation so it will lower the curve of the reaction.

Catalysts lower the activation barrier, so a greater fraction of reactants can cross the new lower barrier and convert into products.

The way a catalyst lowers the activation energy is by creating a completely new path to get to the products, which has a lower activation energy.

A catalyst will lower the activation energy (Ea) in a reaction, causing the curve of the rxn process vs energy graph curve to be lower than without a catalyst.

does this affect the reverse reaction too?

the curve is going to be lowered because the activation energy will be lowered

Catalysts lower the activation energy, so the way I like to think about it, on a graph, the reaction with a catalyst will have a smaller "hump" than the reaction without a catalyst. This is what speeds up the reaction.

Catalysts reduce the amount of activation energy required for the reaction to proceed.

A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.

Hi,
Since catalysts speed up a reaction, the activation energy is lowered. So graphically, the addition of a catalyst lowers the overall curve.

Catalysts lower the activation energy needed in order for a reaction to take place. By doing so, the reaction requires less energy in order to occur which helps to speed up the reaction rate of a reaction.

Catalysts work be reducing the activation energy of a reaction, so it occurs "earlier" than if it was uncatalyzed, speeding up reaction rate.

Both catalysts and enzymes decrease the activation energy of a reaction so they will make the reaction faster that way.

catalysts redirect the steps of the reaction, enable a path with intermediate complexes that are more thermodynamically favorable than if the catalyst is not involved. This means at any given time at a specific temperature, more complex can be formed, and more reaction can be carried out, making the rate of reaction higher.

Hellp!

Catalysts lower the activation energy and therefore make the "hump" in the curve appear earlier.

A catalyst lowers the activation energy, thus accelerating the reaction.
