← ScienceWhich outcome occurs when gaseous reactants pass over platinum?
A)Reaction rate increases significantly.✓
B)Activation energy increases notably.
C)Equilibrium constant value decreases.
D)Reactant kinetic energy decreases gently.
💡 Explanation
The reaction rate increases significantly because platinum acts through surface adsorption, providing an alternative reaction pathway with lower Activation Energy leading to Heterogeneous Catalysis, which accelerates reaction rate. Therefore, rate rise, rather than energy changes or equilibrium changes under these specific conditions..
