How does a catalyst work?

Catalysts function by supplying a (different) system with a lower activation energy and a different transition state. As a result, there are more molecular collisions that have the energy to enter the transition state. As a result, catalysts may facilitate reactions that would otherwise be slowed or stopped by a kinetic barrier.

Explanation:

I’m guessing in “your own words” so here goes nothing: Catalysts work by giving an (elective) system including an alternate progress state and lower initiation energy.

Explanation:

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
