given the enthalpies of reaction below.
a) ‐1567.4 kJ b) ‐41.0 kJ c) +1.054 kJ d) +41.0 kJ e) +1567.4 kJ I also accepted (b) because the word “condensation” refers to the opposite reaction. I missed it when reversing the reaction to make the second version of the question.
using standard molar enthalpies of formation. molecule Δ Hf ° (kJ/mol) CH 3 OCH 3 (g) ‐184. CO 2 (g) ‐393. H 2 O(A)^ ‐285. a) ‐76.4 kJ b) ‐495.2 kJ c) ‐863.4 kJ d) ‐1460.3 kJ e) ‐1828.5 kJ
