Which outcome arises when improperly refined saltpeter reacted in early Chinese gunpowder?

💡 Explanation

Reduced combustion energy occurs because increased impurities affect crystalline bonds, reducing the deflagration FRONT propagation during the Redox reaction, therefore saltpeter impurities impeded the combustion energy, rather than affecting ballistics.
