The enthalpy change involved in the oxidation of glucose is `-2880 kJ mol^-1`. Twenty five percent of this energy is available for muscular work. If 100 kJ of muscular work is needed to walk one kilomtere, what is the maximum distance that a person will be able to walk after eating 120 g of glucose?

The change in enthalpy due to combustion of glucose is 2880 " kJ mol"^(-1) . 25% of this energy is utilised by the body muscles to do physical work. If 100 kJ of energy is used by the muscles to walk 1 km then what will be the maximum distance a person can walk after consuming 120 g of glucose ?

If 150 kJ of energy is needed for muscular work to walk a distance of 1 km, then how much of glucose one has to consume to walk a distance of 5 km, provided only 30% of energy is available for muscular work. The enthalpy of combustion of glucose is 3000 kJ mol^-1
