← ScienceWhich risk increases when a rocket propellant tank develops microfractures?
A)Catalytic decomposition accelerates quickly✓
B)Rapid unplanned dissembly occurs
C)Adiabatic compression spontaneously initiates
D)Molecular oxygen embrittlement spreads
💡 Explanation
Microfractures increase surface area; therefore, surface-catalyzed decomposition rapidly accelerates because increased surface contact provides more reaction sites. This can lead to uncontrolled releases and explosions, rather than spontaneous compression or oxygen embrittlement.
