How do you think those buildings stand up against the forces of the waves? Describe what you think
happens to buildings exposed to sea erosion and then suggest ways that the destruction associated with
this force can be stopped for people who live in towns near the coast. Be sure to have both parts in your
answer!

i it is d i hope it

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
