Question

Quizplus · Accepted Answer

To find the respiratory quotient (RQ), we need to determine the ratio of carbon dioxide produced to oxygen consumed during respiration. From the balanced equation, we see that for every molecule of stearic acid consumed, 26 molecules of oxygen are consumed and 18 molecules of carbon dioxide are produced. 
Therefore, RQ = (CO2 produced)/(O2 consumed) = 18/26 = 0.69. 
The correct answer is B.
