Which consequence results when a rocket propellant's binder degrades?

A)Uncontrolled chain polymerization initiation
B)Inconsistent combustion rate develops
C)Increased nozzle erosion observed
D)Cryogenic fuel spontaneous vaporization

💡 Explanation

Non-uniform combustion occurs because binder degradation weakens **Van der Waals forces** and cohesion. Therefore, the burn rate varies undesirably, rather than auto-ignition or nozzle erosion which depend on other parameters.
