    RQ (Respiratory Quotient) is defined as

    A)  volume of \[C{{O}_{2}}\] evolved = volume of \[{{O}_{2}}\]consumed

    B) \[\frac{\text{volume of }{{\text{O}}_{2}}\text{ consumed}}{volume\,of\,C{{O}_{2}}volved}\]

    C) \[\frac{\text{volume of C}{{\text{O}}_{2}}\text{ evolved}}{volume\,of\,{{O}_{2}}onsumed}\]

    D) \[\frac{\text{volume of }{{\text{O}}_{2}}\text{ evolved}}{volume\,of\,C{{O}_{2}}consumed}\]

    Correct Answer: C

    Solution :

                    The ratio of \[C{{O}_{2}}\] formed and \[{{O}_{2}}\] utilised during complete combustion of fuel substances is called respiratory quotient. RQ can be measured by Ganong's respirometer. \[RQ=\frac{\text{Volume of C}{{\text{O}}_{\text{2}}}\text{ evolved}}{Volume\,of\,{{O}_{2}}consumed}\]
