Use the Arrhenius equation and solve for Ea. You might use for k something like 1 L sours/64 hours etc.
Use the same equation again but change the T to 37. Post your work if you get stuck.
At room temperature (about 20C) milk turns sour in about 64 hours. In a refrigerator at 3C, milk can be stored for about three times as long before turning sour. (i) Determine the approximate activation energy for the reaction that causes milk to sour, and (ii) estimate how long it would take for milk to sour at 37C.

I guess I just don't know what value to use for A in the Arrhenius equation.
Usually when one doesn't know the value of A we substitute 1 for it. These are estimates anyway.
