EqCalc‑G is an educational and engineering reference tool for calculating gaseous chemical equilibrium using Gibbs free‑energy minimization. Designed for students, researchers, and practicing engineers, the app provides a fast, portable way to explore equilibrium behavior in hydrogen and hydrocarbon systems under ideal‑gas assumptions. Key Features: • Includes a publicly available thermochemical dataset derived from NASA curve‑fits of the NIST‑JANAF tables for selected species • Import your own thermochemical datasets in Aerotherm, Chemkin, or NASA CEA formats • Flexible reactant specification:
 - Define mixtures on a mole or mass basis - Or specify fuel mixture, air, and fuel‑air equivalence ratio • Export results easily by copying output to the clipboard for use in your favorite notes or spreadsheet apps Basic vs. Plus Version: The free Basic version supports fixed enthalpy and pressure equilibrium calculations.
Upgrade to Plus version to unlock additional problem types: • Fixed temperature & pressure • Fixed entropy & pressure • Fixed internal energy & volume • Fixed temperature & volume • Fixed entropy & volume NASA/NIST Notice: Use of NASA and NIST thermochemical data does not imply endorsement, certification, recommendation, or approval of this app, its developer, or any results produced.
