You are on the scene of a patient who is the victim of an assault. the scene is safe. you find a 22-year-old male patient responsive to painful stimuli only. his blood pressure is 180/80, pulse is 60, respirations are 12, and his oxygen saturation is 95 percent on room air. how would you classify this patient and why?

hello there,

guys i’m confused.

which rock will weather faster?

answer: b rock

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.
