Q10 coefficient
2.1
Temperature difference
10 °C
Rate ratio R₂/R₁
2.1
Reading
Typical for many enzymatic and chemical processes
Predicted rate 10 °C higher
44.1
A temperature difference is the same number in °C and K, so either scale works here. Q10 near 2 to 3 is normal for enzyme-driven processes within their working range.
What this calculator does
Measures how strongly a rate depends on temperature, expressed as the factor per 10 degree rise.
What your result means
Q10 near 2 to 3 is typical of enzyme-driven and many chemical processes.
Formula and working
Q10 = (R₂ / R₁)^(10 / (T₂ − T₁))
- 1
Collect the inputs
Rate at the lower temperature (R₁) = 10; Lower temperature (T₁) = 20 °C; Rate at the higher temperature (R₂) = 21; Higher temperature (T₂) = 30 °C
- 2
Apply the formula
Q10 = (R₂ / R₁)^(10 / (T₂ − T₁))
- 3
Result
Q10 coefficient = 2.1
