The present work is dedicated to show that there are relationships between the absolute chemical hardness (η) of monopropellants and their specific impulse (Is). A total of sixteen monopropellants have been modelled and the absolute hardness obtained by quantum chemical calculations. The following equation was obtained: Is = 17.562 η + 125.551, providing specific impulse results in very good agreement with reference values.
