Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck on what should be a reasonably simple question...here it is:

The quality of a certain supermarket product depends on a single thermally

activated process. It can be stored safely for 3 days at 17 degrees C, but only one day at 37 degrees C. How long can it be stored at 0 degrees C?

I know this has something to do with a boltzmann distribution, and possibly to do with putting it in the form of a lifetime...but i'm unsure of the lifetime method...is that where you say: t = 1/probability of decay ???

At a guess I would from this have said that there is some activation energy E, and used boltzmann distribution integrated from E to infinity over all Energy to find the probability that a particle has enough energy to decay (or whatever).

And then use t=1/p and the given values to compute E, and then plug it back in to find the t for the new T.

Whether that is right or not, can someone step through the stages for me?

Thanks!!!
