Rate of reactions?
the activation energy for the reation involved in the souring of milk is 75kJ. Milk will sour in about 8 hrs. at 21 degrees C. How long will raw milk last at a maintained temp. of 5 degree C? Assume the rate constant to be inversely related to souring time...
Details please..
Answer:
You need to use the Arrhenius equation:
k = A*e^(Ea/RT)
Use the first condition to solve for the Arrhenius prefactor. Then, solve for the rate using the lower temperature. Don't forget to convert to Kelvins. And use the right value of R (8.31 J/mol*K).
