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.

Catalysts lower the curve of the reaction.

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
