A)Quantum entanglement alters atomic distances
B)Increased kinetic energy overcomes activation barrier✓
C)Solvent polarity induces reactant aggregation
D)Catalyst surface area decreases at higher temperature
💡 Explanation
The temperature dependence arises because increasing temperature raises the average kinetic energy of reactant molecules; therefore, more collisions possess sufficient energy to surmount the Arrhenius activation energy barrier, leading to an increased reaction rate, rather than altering atomic distances through quantum entanglement.
