### catalyst

how would a catalyst lower the activation energy of the transition state?

### Re: catalyst

Catalysts provide an alternate pathway for the reactants which requires less energy than without them.

### Re: catalyst

Some catalysts provide a way for the reacting species to undergo productive collisions more frequently, therefore less energy is needed to initiate the reaction. (Same thing as lowering the activation energy).

### Re: catalyst

The catalyst provides a different path for reactants to end up at the same products. Increased collisions allow it to proceed with less energy.

### Re: catalyst

think of "lowering the activation energy" as "it makes it easier for the reaction to occur" its like extra help for the products to undergo a reaction.
