Explain Enthalpy of combustion.

Explain Enthalpy of fusion.

Can enthalpy of combustion be positive ?

Define heat of combustion.

Standard molar enthalpy of combustion of glucose is -2880 kJ. If only 25% of energy is available for muscular work and 1.0 km walk consumes 90 kJ of energy, what maximum distance (in km) a person can walk after eating 90 g of glucose.

Define enthalpy of solution.

Define the term enthalpy of combustion. What is its signification ?

Explain Enthalpy of neutralisation.

Explain the following Enthalpy of fusion

The standard enthalpy of formation of octane (C_(8)H_(18)) is -250kJ //mol . Calculate the enthalpy of combustion of C_(8)H_(18) . The enthalpy of formation of CO_(2)(g) and H_(2)O(l) are -394 kJ//mol and -286kJ//mol respectively.
