Well, in the Haber process, increasing pressure pushes the equilibrium to make more ammonia, because you're squeezing those N₂ and H₂ molecules together! But raising temperature? Actually *lowers* the yield because the forward reaction is exothermic... but we still run it hot, yaar, around 450°C, because the catalyst needs that heat to work fast enough to be economical. And that iron catalyst? Doesn't shift equilibrium at all, but gets us to that equilibrium much faster—saving us time and money! Honestly, I see this every shift: we balance these factors not for perfect yield, but for the best profit, just like I balance my car's fuel efficiency and rental costs to send money home.
