How can carbon skeletons vary?

Explanation:

. . . And besides, it is not improbable that some scrupulous people might be apt to censure such a practice, (although indeed very unjustly) as a little bordering upon cruelty, which, I confess, hath always been with me the strongest objection against any project, how well soever intended.

Swift uses understatement and irony when he says his plan is “a little bordering on cruelty” to highlight how cruel the plan really is.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

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.
