Real World
Catalytic converters in cars use platinum and palladium as heterogeneous catalysts to convert toxic CO and NOₓ into CO₂ and N₂ — the metals provide a surface for adsorption, lowering Ea without being consumed.
Exam Focus
Always state that a catalyst provides an alternative reaction pathway with lower activation energy — do not just say 'lowers activation energy' without the pathway reference.
