Question

The R.Q. value of oxalic acid is

• A. 1
• B. 0.7
• C. 4
• D. $\infty$
• E. 1.5

Answer 1

The correct option is C 4

The respiratory quotient is defined as the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time. Reaction of oxidation of oxalic acid is as follows.

2$C_2{H}_2{O}_4$ + $O_2$ ---> 4$C{O}_2$ + 2$H_{2}O$

R.Q= $C{O}_2$/$O_2$ = 4/1 = 4.

So, the correct answer is option C.
