🤓 Based on our data, we think this question is relevant for Professor Khajo's class at CCNY.
Recall that the equation for ΔH°rxn is:
(products) = sum of ΔH°f of products
(reactants) = sum of ΔH°f of reactants
For this problem, we are asked the find the reaction where ΔH°rxn is equal to ΔH°f of the product(s).
For which of the following reactions is ΔH°rxn equal to ΔH°f of the product(s)?
2Na(s) + Cl2(g) → 2NaCl(s)
H2(g) + 12O2(g) → H2O(g)
Na(s) + 12Cl2(g) → NaCl(s)
H2O2(g) → 12O2(g) + H2O(g)
2H2(g) + O2(g) → 2H2O(g)
Na(s) + 12Cl2(l) → NaCl(s)
