How do you assess "fear of failure" in your own life? Give an example of you removing the "fear of failure" in your life. Hint: Think about something you were scared to do but then, you were brave and didn't let the fear take control.

airlines i think? or a cruise boat? does this work out for u? ?

wegner's theory did not explain how the continents could move

explanation:

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.
