What is a non-renewable resource? A. A resource that has already been used up
B. A resource that is infinitely abundant
C. A resource generated at a rate that is much faster than it is used
D. A resource generated at a rate that is much slower than it is used

c. is the correct answer

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.

i think that it is c, d, and e, hope this
