Which outcome occurs when a catalyst introduces unoccupied molecular orbitals into a reaction pathway?

💡 Explanation

When a catalyst introduces unoccupied molecular orbitals, a new reaction pathway with a lower energy transition state forms because the catalyst facilitates a different, more stable, intermediate. Therefore, the activation energy reduces, rather than changing equilibrium, abolishing temperature dependence, or decreasing enthalpy change, which alter fundamental thermodynamic properties.
