Equilibrium study based on mass action law is performed to find the insights of extraction mechanisms, equilibrium constant (K = 295.12 k·mol?1) and stoichiometry (m:n = 1:1) as also confirmed by FTIR. Thermodynamic parameters, enthalpy (?H°), and entropy (?S°) are determined 27.51 K J mol?1 and ?50.21 J mol?1 K?1, respectively. © 2018, © 2018 Taylor & Francis Group, LLC.eninfo:eu-repo/semantics/closedAccessCOSMO-RS and thermodynamicsequilibriap-Nitro phenol (PNP)reactive extractionArticle10.1080/01496395.2018.15522942-s2.0-85058371237274816Q2273854
