Which risk increases when temperature drops dramatically across a platinum catalyst?

A)Thermal shock induces surface cracking
B)Catalyst inhibits CO oxidation activity
C)Platinum undergoes phase transformation now
D)Equilibrium shifts toward adsorbed reactants

💡 Explanation

Decreasing temperatures subjects platinum to thermal gradients causing thermal shock to lead to surface cracking; because high stresses concentrate at grain boundaries; therefore cracking occurs rather than only phase transition because the drop is sudden.
