Which outcome arises when an ancient Chinese crossbow uses poorly refined gunpowder, affecting its firing range?

💡 Explanation

Increased misfire rate occurs when improperly refined gunpowder contains inconsistent particle sizes. Inconsistent particle sizes reduce the speed of deflagration, because a less consistent mixture inhibits rapid combustion; therefore, misfires happen rather than achieving optimal bolt propulsion which occurs with uniformly refined gunpowder.
