In an investigation into the cellular respiration of baker's yeast (Saccharomyces cerevisiae), the rate of carbon dioxide production was measured at two different incubation temperatures to evaluate metabolic efficiency.

At a temperature of $15∘C15^\circ\text{C}$ , the rate of carbon dioxide production was 3.2 cm³ min^-1. At a temperature of $25∘C25^\circ\text{C}$ , the rate of carbon dioxide production was 8.8 cm³ min^-1.

The temperature coefficient ( $Q_{10}$ ) is calculated using the formula:

Q_{10} = \frac{\text{rate at higher temperature}}{\text{rate at lower temperature}}

What is the $Q_{10}$ value for this biological process over this temperature range?
