← ScienceWhich outcome results when excess thermal energy input circumvents a catalyst?
A)Nonselective products form more readily✓
B)Equilibrium shifts towards reactant favor
C)Reaction's activation energy remains unchanged
D)Catalyst efficiency proportionately always improves
💡 Explanation
If high thermal energy overcomes kinetic barriers, reactions proceed via alternative, non-catalyzed pathways. This bypasses the intended **catalysis mechanism** controlling selectivity; therefore, nonspecific products appear, rather than the catalyst enhancing selectivity.
