Question #205205

The standard heats of formation, delta Hf, fro C2H4 is +52.3KJ/mole. If C2H4 (ethylene) reacts with H2 to produce C2H6 (ethane) according to the following equation:

C2H4+H2=C2H6 deltaH=-137KJ

What is the heat of formation of C2H6?

Gives

"C_2H_2+H_2\\rightarrow C_2H_6"

"\u2206H=\u2206H_{rec}-\u2206H_{pro}"


"\u2206H_{rec}=(52.3-0)kJ\/mol=52.3KJ\/mol"

"\u2206H_{pro}=?"

"\u2206H_{c_2H_6}=?"

"\u2206H=-137kJ"

"\u2206H_{c_2H_6}=\u2206H_{rec}-\u2206H"


"\u2206H_{c_2H_6}=(52.3kJ\/mol)\\times1mol-(-137)=189.3kJ"
