We constructed a Jones‐Wilkins‐Lee (JWL) equation of state (EOS) for the PBX 9502 detonation products based on a standard one by lowering the Chapman‐Jouguet (CJ) pressure. We found that a slow component exists in the chemical reaction rate, and the global hydrodynamic behavior as exhibited by the standard EOS reflects such an effect. By reducing the CJ pressure, we effectively remove the contribution of the slow reaction from the standard EOS, and the new EOS should represent the detonation products better. In conjunction with a reactive burn model which includes a slow component, the products EOS performs better than the standard EOS.
