Temperature Coefficient Q₁₀ Calculator
🔑 Enzymes & reaction rates. Use the Temperature coefficient Q₁₀ formula to find q₁₀, rate 10 °c warmer, rate at the lower temperature: pick the value you want, type the others, and the answer updates as you go.
Around 2 for most enzyme reactions below their optimum.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Q₁₀ | no unit |
| Rate 10 °C warmer | no unit |
| Rate at the lower temperature | no unit |
Worked example
Find the q₁₀ when Rate 10 °C warmer = 16, Rate at the lower temperature = 8.
Using Q10 = rate at (T + 10) °Crate at T °C: Q₁₀ = 2.
Frequently asked questions
What is the formula for Temperature coefficient Q₁₀?
Q10 = rate at (T + 10) °Crate at T °C. Around 2 for most enzyme reactions below their optimum.
What do the letters stand for, and what units are used?
Q₁₀, Rate 10 °C warmer, Rate at the lower temperature.
How do you calculate q₁₀?
Put the values into Q10 = rate at (T + 10) °Crate at T °C. For example, with Rate 10 °C warmer = 16, Rate at the lower temperature = 8, q₁₀ = 2.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (q₁₀, rate 10 °c warmer, rate at the lower temperature) and fill in the others: it rearranges the formula for you.
