JohanFourie Posted July 11, 2019 Share Posted July 11, 2019 Hi Brian We struggle to write a script in Chemplugin for the reaction rate of kinetic minerals. The script for dolomite is given below. Python also don't like the double notation: "H+" for the parameters. "kinetic Dolomite-Mn 12.1 volume% rate_law = script 'rate = (1.49e-02*EXP(-29000/(8.3144598*TK))*activity("H+")^0.75 + 1.00e-02*EXP(-34800/(8.3144598*TK))*activity("H2CO3")^0.75 + 2.20e-7*EXP(-52200/(8.3144598*TK))*activity("H2O")^0.75) * surface * (1 - QoverK) RETURN rate' pre-exp = ??? act_eng = ??? surface = .65" We would appreciate your help.
