Do catalysts increase the rate of a chemical reaction by raising the activation energy of a chemical reaction?

Answer 1

in fact, it lowers the activation energy so by doing so it increases the rate of the reaction.

Answer 2

Catalysts do not raise the activation energy of a chemical reaction, they decrease it. Activation energy is how much energy two molecules must have at the beginning of a particular reaction. Increasing the activation energy would mean that the reaction happens much more slowly.

Decreasing activation energy increases the rate of the reaction.

Answer 3

B. A catalyst works by using offering an selection reaction pathway to the reaction product. the value of the reaction is greater suitable as this selection course has a decrease activation power than the reaction course not mediated by using the catalyst

Answer 4

no, actually, a catalyst lowers the activation energy, so that the reaction's rate speeds up

Answer 5

Many reaction have a sequence of events, which goes: reactants -> [intermediate] -> products.
The transition from reactant to intermediate requires an "energy hump" to be negotiated. The catalyst lowers this hump, allowing that part of the reaction sequence to proceed faster.
