Which risk increases when a rocket propellant's molecular nitrogen concentration rises?

A)Reduced combustion chamber temperature
B)Premature fuel-oxidizer separation
C)Elevated injector plate corrosion
D)Combustion instability due to diffusion

💡 Explanation

Combustion instability increases because Rayleigh's criterion predicts instability from higher pressure oscillations coinciding with heat release, driven by accelerated molecular diffusion of nitrogen. Decreased temperature is less likely; therefore, instability, rather than stable burning, will result due to nitrogen presence.
