TestHub · Accepted Answer

The respiratory quotient (RQ) is defined as the ratio of the volume of carbon dioxide evolved to the volume of oxygen consumed during respiration.

From the given balanced chemical equation:
Volume of $CO_{2}$ evolved $= 102$
Volume of $O_{2}$ consumed $= 145$

$RQ = \frac{102}{145} \approx 0.7$

The calculated value of RQ is approximately $0.7$ , which lies between $0.5$ and $0.95$ .

Answer: Between $0.5$ and $0.95$
