Organic hydrogenation reactions, in which H2 and an unsaturated organic compound

Question

Organic hydrogenation reactions, in which H2 and an unsaturated organic compound combine, are used in the food, fuel, and polymer industries. In the simplest case, ethene (C2H4) and H2 form ethane (C2H6). If 150. kJ is given off per mole of C2H4 reacting, how much heat is released when 14.6 kg of C2H6 forms? 78214 kJ Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry 3 out all intermediate results to at least four-digit accuracy to minimize roundoff error.

Explanation / Answer

Answer: 73000 kJ

no.of moles = 14.6*1000/(28+6) =468.67 moles

Total heat released = 150*468.67 =73000kJ
