Standard molar enthalpies of elements in their most stable forms at K and atm are zero. Example 15-5: The standard molar enthalpy of formation for phosphoric acid is kJ/mol. Write the equation for the reaction for which \uf044Horxn = kJ. P in standard state is P4. Phosphoric acid in standard state is H3PO4(s) 3/2 H2(g) + 2 O2(g) + 1/4 P4(s) \uf022 H3PO4(s) kJ. \uf044HofH3PO4 = kJ/mol.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
