Question
Chemistry Due to E. coli outbreak in spinach, USDA recommends that we boil spinach in water before consumption. We learned that 2 major reactions occur when we boil spinach: 1) the reaction that kills E. coli, and 2) the reaction that turns the fresh green color into unpleasant dark green. We know that the activation energy for the 1st reaction is around 240 kJ/gmol, and the activation energy for the 2nd reaction is about 96 kJ/gmol. We also know in the city that the boiling temperature of water is 100°C, while in a house at the top of a mountain water boils at 90°C. To achieve the same log reduction of E.coli at both places, at which place would the original fresh green color of spinach be likely better preserved?
