本文针对化学平衡教学中较高计量系数复杂化学反应平衡计算解析求解困难的问题，以合成氨反应平衡转化率为研究对象，结合吉布斯函数判据、范特霍夫方程及勒夏特列定律，揭示了温度、压力对反应平衡调节的定性及定量规律。为突破传统教学多分子反应转化率计算瓶颈，引入Aspen HYSYS软件的Gibbs反应器模块，构建数字化实验平台，基于PR-Twu物性包的真实气体逸度修正，模拟了450-550℃和20-30 MPa工况下的氢气转化率，并与理想气体假设理论值相比较。结果表明：高压下逸度效应显著(如30 MPa/450℃时模拟转化率49.3%vs.理论最高转化率62.9%)，证明理想模型在高压体系中失效；温度升高使合成氨转化率降低，压力增大则提升合成氨转化率。本研究通过数字化工具直观验证了热力学理论，为化学平衡教学提供了数据化的实践路径。
