Which outcome occurs to reaction rate when positive catalysts lower activation?

A)Increased frequency of successful collisions
B)Decreased entropy within reaction vessel
C)Higher intermediate state energy plateau
D)Reduced product yield at equilibrium

💡 Explanation

The reaction rate increases because catalysts lower activation energy by providing alternate reaction pathways that require less energy; therefore, more molecules have sufficient energy to react, rather than facing unchanged prior higher activation energy.
