# Fermentation of glucose

Chemistry Level pending

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy from the formation of $$1$$ mole of the compound from its constituent elements, with all substances in their standard states at $$101.3$$ kPa and $$298$$ K. The above shows the enthalpy change in formentation of glucose(C$$_6$$H$$_{12}$$O$$_6$$) to produce ethanol(C$$_2$$H$$_5$$OH). Which of the following statements is correct?

a) The standard heat of formation of C$$_6$$H$$_{12}$$O$$_6$$($$s$$) ($$\Delta$$H) is $$-1260$$ kJ/mol.
b) The standard heat of formation of C$$_2$$H$$_5$$OH($$l$$) ($$\Delta$$H) can be calculated from the above data.
c) The standard enthalpy of reaction($$\Delta$$H) when $$1$$ mol of C$$_6$$H$$_{12}$$O$$_6$$($$s$$) is fermented to produce C$$_2$$H$$_5$$OH($$l$$) and CO$$_2$$($$g$$) is $$82$$ kJ.
