Which outcome results when the proportion of sulfur increases beyond a critical threshold in early gunpowder formulations?

💡 Explanation

Decreasing projectile speeds occurs due to sulfur acting as a moderator, reducing the deflagration rate. The sulfur undergoes Chemical Inhibition, slowing combustion propagation, because it reduces hot radical production, therefore muzzle velocity drops, rather than increasing cannon pressures or binder degradation.
