We are being asked to determine which of the following reactions is ΔH°rxn equal to ΔH°f of the product(s)
Recall that enthalpy of reaction is given by the equation
So for ΔH°rxn = ΔH°f, product,
For which of the following reactions is ΔH∘rxn equal to ΔH∘f of the product(s)? You do not need to look up any values to answer this question. Check all that apply.
a) Li(s)+12F2(g)→LiF(s)
b) Li(s)+12F2(l)→LiF(s)
c) H2O2(g)→12O2(g)+H2O(g)
d) 2H2(g)+O2(g)→2H2O(g)
e) 2Li(s)+F2(g)→2LiF(s)
f) H2(g)+12O2(g)→H2O(g)
