The enthalpy change involved in the oxidation of glucose is `-3000kJ mol^(-1)` . `25%` of this energy is available for muscular work. If `100kJ `of muscular work is needed to walk 1 kilometer, what is the maximum distance that a person will be able to walk after eating `144g` flucose ?

Text Solution

Verified by Experts

The correct Answer is:
6
Energy available for muscular work
`=(3000xx25)/(100)=750kJ mol^(-1)`
`:. ` Energy available for muscular work for ltbr. `120g` glucose `=(750xx144)/(180)=600kJ`
`:. 100kJ` is used in 1 kilometer distance
`:. 600kJ` is used in `=(600)/(100)=6.0km`
