Problem: Using the data in Appendix G, calculate the standard enthalpy change for the following reaction:(a) Si(s) + 2F2(g) ⟶ SiF4(g) ΔH°SiF4 = -1615 kJ/mol 

FREE Expert Solution
  • ΔH°rxn can be solved by getting the difference of ΣΔHproducts and ΣΔHreactions. Equation will appear as

  • Recall that the standard molar enthalpies for elements in their standard form (pure form in natural conditions) will always be 0.
