Which outcome results when an improperly inhibited polymerization reaction self-accelerates?

A)Exothermic runaway raises internal temperature
B)Reaction shifts toward thermodynamic equilibrium
C)Activation energy undergoes quantum tunneling
D)Rate constant diminishes proportionally over time

💡 Explanation

Uninhibited polymerization's **autoacceleration** releases more heat, becoming exothermic faster because the generated heat raises the temperature, disproportionately accelerating free-radical formation and thus creating a runaway reaction; therefore, rapid temperature increase will happen rather than equilibrium shift or quantum tunneling.
