How can you find heat of formation of water?
Heat of formation of compounds is the fraction of heat evolved or absorbed when 1 mole of the substance is directly obtained from its constituent elements. Usually the conditions at which the compound is formed are taken to be temperature of 25 ∘ C and pressure of 1 atm in which case the heat of formation is called as standard heat of formation. ΔH=sum of bond energy of reactants−bond energy of products Complete step by step answer: As we know during any reaction evolution or absorption of heat energy occurs. This is in accordance with law of conservation of energy (1st law of thermodynamics) enthalpy of formation or heat of formation is the fraction of heat evolved or absorbed when 1 mole of substance is directly obtained from its constituent elements. To obtain enthalpy of formation of water H2(g)+1/2O2(g)→H2O(g)→ΔH=?H2(g)+1/2O2(g)→H2O(g)→ΔH=? for this you should know the bond energies of the reactants and products. BE-Bond Energy ΔH=[BE of H2+1/...
