Question

1. Use the data in Table 8.3 on page 289 in the textbook to calculate an approximate ΔH degrees in kilojoules for the industrial synthesis of ethyl alcohol from ethylene: C2H4(g) + H202 (g) = C2H5OH(G)

C-H 410 H-0 460 C-O 350 C=O 732 O-H 460

2. How much heat is absorbed/released when 20.00 g of NH₃(g) reacts in the presence of excess O₂(g) to produce NO(g) and H₂O(l) according to the following chemical equation?

4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(l)

ΔH° = +1168 kJ
