⚡ Enter ArenaWhat causes the rate of a catalyzed chemical reaction to accelerate markedly even with a relatively small decrease in activation energy?
A)Increased reactant diffusion constant
B)Enhanced product equilibrium constant
C)Exponential increase in reactive collisions✓
D)Decreased reactant thermodynamic stability
💡 Explanation
The reaction rate is exponentially dependent on the activation energy according to the Arrhenius equation. Because a catalyst lowers the activation energy, the number of molecules with sufficient energy to react increases exponentially, therefore the reaction rate accelerates dramatically rather than linearly.
