← ScienceWhich outcome occurs more rapidly with catalysts in a fixed-volume batch reactor?
A)Equilibrium achieved with lower activation energy✓
B)Increased product selectivity for endothermic reactions
C)Lower overall reaction enthalpy change observed
D)Higher reactant conversion at standard pressure
💡 Explanation
A catalyst lowers a reaction's activation energy via the mechanism of surface adsorption, causing the reactants to reach the transition state faster; therefore, the equilibrium is achieved significantly sooner, rather than altering reaction pathways leading to different products or enthalpy.
