Holy cow! The process of raw milk spoiling is described by the reaction below: multiple steps C12H22011(aq) + H20(1) → 4 C3H6O3(aq) a. At 28 °C, raw milk sours in 3.9 h but takes 44 h to sour in a refrigerator at 5 °C. If this is a first order reaction, estimate the activation energy in kJ/mol for the reaction that leads to the souring of milk. Hint: for a first order reaction, think about what the units are for k.

13. Holy cow! The process of raw milk spoiling is described by the reaction below: multiple steps C12H22011(aq) + H,0(1) 4 C3H,O3(aq) a. At 28 °C, raw milk sours in 3.9 h but takes 44 h to sour in a refrigerator at 5 °C. If this is a first order reaction, estimate the activation energy in kJ/mol for the reaction that leads to the souring of milk. Hint: for a first order reaction, think about what the units are for k. b. Draw two simple, one-step reaction energy diagrams of raw milk spoiling and milk that contains preservatives spoiling. Assume that this process is endothermic. c. What is the vapor pressure of solution when 12.0 g of lactose (C1»H22011) is added to 165.0 g of water? Consider the vapor pressure of pure water is 23.36 mmHg.
