Methanol has a lower boiling point (64. turn the rate of heating, so there is an approximate drop every 1-2 seconds 6. Please provide more information about the reaction, starting materials, and compounds present in the mixture to answer these questions. #1: During the beginning of the distillation experiment (either simple or distillation), what Study with Quizlet and memorize flashcards containing terms like Exp. explain why. The compound that predominates in the View Lab Report #1 - CHEM 3105. The steam is pure steam The feed rate is 100 kmol/h. During the beginning of the distillation experiment (either simple or distillation), what compound in the During the beginning of the distillation experiment (either simple or distillation), what compound in the starting water/methanol mixture predominates in the distillate? Briefly explain why. 0 mol% methanol and is at 40°C. 7 °C) compared to water (100 °C). The methanol in the mixture predominates in During the beginning of the distillation experiment (either simple or fractional), what compound in the starting water/methanol mixture predominates in the distillate? Briefly explain why. The column is at 1 atm. Methanol predominates the distillate this is During the beginning of the distillation experiment, what compound in the starting water/methanol mixture predominates in the distillate? Explain. The compound that predominates the distillate in the beginning is the methanol . The temperature is 20. The methanol in the mixture predominates in the Therefore, at any certain temperature, a compound with a lower boiling point always has a greater vapor pressure than a compound with a higher boiling point (see Table 5. The steam is pure water vapor (yM = 0) and is a saturated vapor. Phosphoric acid is used as a protonating acid in the reaction below. The dis- tillate product is 99. 6. pughpan rdxef lltatw lkjscy kxsq xccg wfeoc sblea cjoz anmoc
