Acetic acid, CH3COOH, is contained in vinegar. Suppose acetic acid was formed from its elements, according to the following equation:
2C(graphite) + 2H2(g) + O2(g) †’ CH3COOH(l)
Find the enthalpy change, ˆ†H, for this reaction, using the following data:
CH3COOH(l) + 2O2(g) †’ 2CO2(g) + 2H2O(l);
ˆ†H = €“874 kJ
C(graphite) + O2(g) †’ CO2(g); ˆ†H = €“394 kJ
