← ScienceWhich 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.
