← ScienceWhich outcome would occur if a catalyst changes the symmetry of reacting molecule's frontier orbitals?
A)Increased reaction rate via orbital overlap✓
B)Decreased product selectivity due to side reactions
C)Inhibition via competitive adsorption blocking
D)Exothermic shift due to transition state energy
💡 Explanation
When a catalyst modifies frontier orbital symmetry, constructive orbital overlap increases because the catalyst facilitates the formation of a lower energy transition state, increasing reaction rate. Therefore, increased reaction rate from better orbital overlap results, rather than reduced selectivity, inhibition, or exothermic shift that require alternative mechanistic constraints.
