The standard enthalpies of formation ofCO2(g) , H2O(l) and glucose (s)

1.	The standard enthalpies of formation ofCO2(g) , H2O(l) and glucose (s) at 25° C are –400 kJ/mole, – 300 kJ/mole, –1300 kJ./molerespectively. The standard enthalpy ofcombustion per gram of glucose at 25° C is : which formula should be used as enthalpy of combustion is givenenthalpy(product- reactant)enthalpy(reactent-product)also,solve the problem
Answer» The standard enthalpies of formation of CO2(g) , H2O(l) and glucose (s) at 25° C are – 400 kJ/mole, – 300 kJ/mole, –1300 kJ./mole respectively. The standard enthalpy of combustion per gram of glucose at 25° C is : which formula should be used as enthalpy of combustion is given enthalpy(product- reactant) enthalpy(reactent-product) also,solve the problem
