← ScienceWhich consequence results when thermal variations accelerate a chemical reaction past a critical point during polymerization?
A)Explosive runaway reaction (thermal explosion)✓
B)Decreased polymer chain termination rate
C)Increased polymer crystallinity and density
D)Stable, controlled increase in viscosity
💡 Explanation
An explosive outcome arises because increased temperature accelerates radical formation following the Arrhenius equation, rather than allowing heat dissipation. Thermal runaway occurs leading therefore to thermal explosion, rather than slower reactivity at lower temperatures or heat dissipation mechanisms.
