Q10 (temperature coefficient)
From Wikipedia, the free encyclopedia
The Q10 temperature coefficient is a measure of temperature sensitivity based on the chemical reactions.

The Q10 is calculated as:
where;
Rewriting this equation, the assumption behind Q10 is that the reaction rate R depends exponentially on temperature:
Q10 is a unitless quantity, as it is the factor by which a rate changes, and is a useful way to express the temperature dependence of a process.
For most biological systems, the Q10 value is ~ 2 to 3.[1]
