← ScienceWhich risk increases when a chemical reaction's rate constants become highly sensitive to slight temperature variations?
A)Runaway reaction due to positive feedback✓
B)Reduced activation energy of the catalyst
C)Increased equilibrium constant stability
D)Decreased product yield overall observed
💡 Explanation
A runaway reaction occurs because increased temperature proportionally increases reaction rate, which further elevates the temperature if the process is exothermic inducing thermal runaway; therefore positive feedback escalates rapidly rather than reduced catalyst activation energy or shifting equilibrium.
