Question

calculate the enthalpy of hydrogenation of ethylene to ethane ​

Answer 1

Answer:

Thermodynamics. Compute the enthalpy of hydrogenation of ethylene if the bond enthalpies of H – H, C – H, C – C and C = C bonds are 436, 485, 347 and 619 kJ mol–1 respectively. Thus enthalpy of hydrogenation of ethylene is -262 kJ.
