A catalyst provides an alternative pathway with lower activation energy, speeding up both forward and reverse reactions equally, so the equilibrium constant—which depends only on thermodynamics—remains unchanged. My lab synthesizes porous zeolites, and we see this daily: the catalyst doesn't shift where the reaction settles, just how fast it gets there. Reminds me of my TNPSC prep—extra resources might speed my revision, but they can't change the final syllabus or cut-off; the goalpost is fixed, much like that equilibrium constant.
