← ScienceWhich outcome occurs when a catalyst promotes bond formation?
A)Lowered activation energy and accelerated reaction✓
B)Increased reactant concentration, constant rate
C)Elevated temperature; limited product yield
D)Equilibrium shifts disfavoring product formation
💡 Explanation
Lowered activation energy and accelerated reaction happens because a catalyst provides an alternative mechanism, lowering the activation energy; therefore the reaction rate increases rather than being unchanged or favoring the reverse reaction as would changing variables to the system.
