Chemistry

Given the following information, answer these questions.
P₄(g) + 5 O₂(g) â†’P₄O₁₀(s)
Î”Gâ°298â€‰ = âˆ’2748 kJ/mol2 H₂(g) +O₂(g) â†’ 2 H₂O(l)
Î”Gâ°298â€‰ = âˆ’474.2kJ/molP₄O₁₀(s) + 6H₂O(l) â†’ 4H₃PO₄(l)
Î”Gâ°298â€‰ = âˆ’349 kJ/mol
(a)
Determine the standard free energy of formation, Î”Gâ°f(in kJ/mol), for phosphoric acid from this information.(Assume thatÎ”Gâ°298â€‰for all elemental substances is negligible.)
_ kJ/mol
(b)
How does your calculated result compare to the value in theStandard State Thermodynamic Data table? Explain.
The listed value of Î”Gâ°fâ€‰(in kJ/mol) = _kJ/mol.
