If you mean what is the "Rule of Thumb" it is an old law that states a man may beat his wife with a switch, (branch, stick), no bigger around than his "thumb". And we think we are civilized!?!
This is completely wrong. There has never been any such law. The urban legend stems from a court case (not a law) in which the phrase "rule of thumb" never even appears. The judge only mentions that "moderate chastisement" of a wife by her husband is not criminal. Not at all excusable, and the judge was publicly excoriated for his ruling at the time. But this is not the origin of the "rule of thumb." The phrase "rule of thumb" comes from woodworkers using the length of their thumbs for measuring instead of using rulers, and it has been in use at least since the 1600s, long before the supposed "law" about wife-beating. A "rule of thumb" is a convenient approximation.

The general rule of thumb is that the reaction rate will double for each 10ºC change in temperature. So, going from 25 to 50 degrees, would increase the reaction rate APPROXIMATELY by 4.5 times. This is not a law, but just a general rule of thumb for approximating the rate.
