At 28 C, raw milk sours in 4.0 h but takes 48 h to sour in a refrigerator at 5 C. Estimate the activation energy in kJ>mol for the reaction that leads to the souring of milk?
ANSWER:Problem 14.105At 28°C, raw milk sours in 4.0 h but takes 48 h to sour in a refrigerator at 5°C. Estimate theactivation energy in kJ/mol for the reaction that leads to the souring of milk Step-by-step solution Step 1 of 4 Raw (unpasteurized) milk sours in about 4 hours at 28°C (room temperature).Conversion of temperature in terms of kelvin is shown as follows: t°C = (t + 273) KHence, 28°C in terms of Kelvin is as follows:28°C = (28 + 273) K = 301 KAlso, raw milk takes about 48 hours to sour in a refrigerator at 5 °C.Hence, 5°C in terms of Kelvin is as follows:5 °C = (5 + 273) K = 278 K
