Which mechanism reduces activation energy when platinum catalysts promote reactions in catalytic converters of vehicles?

A)Stabilization of transition state intermediates✓

B)Increased kinetic energy of reactant molecules

C)Enhanced reactant concentration on surface

D)Decreased entropy of the reaction mixture

💡 Explanation

When platinum catalysts are present, stabilization of transition state intermediates occurs because the catalyst provides an alternative reaction pathway with lower energy requirements, facilitating the reaction. Therefore transition state stabilization results, rather than increased kinetic energy, higher concentration, entropy decrease which do not actively alter activation energies.
