At room temperature (20 C), milk turns sour in about 64 hours. In a refrigerator at 3 C, milk can be stored 3 times as long before it sours.

At each temperature, the constant K: K= c/(souring time) where c is a constant.

1. Estimate the activation energy of the reaction that causes the souring of milk

2. How long will it take milk to sour at 40 C?
