Web2 C 2 H 2 ( g) + 5 O 2 ( g) → 4 C O 2 ( g) + 2 H 2 O ( l) + 2,599.16 k J The balanced equation shows that 2 moles of C2H2 will produce 4 moles of CO2. From the given information, 52.9 kJ of heat is released. This means the reaction is exothermic, and the heat value should have a negative sign. WebEngineering Chemical Engineering Calculate the heat released (kJ) in the reaction of 3.50 g of acetylene (C2H2) and excess hydrogen gas to form ethane gas: C2H2 (g) + 2H2 (g) …
2C(s)+H2(g)+227.4kJ -> C2H2(g) is an endothermic reaction.
