Calculate the enthalpy of the following reaction : H_(2)C = CH_(2)(g) + H_(2)(g) rarr H_(3)C - CH_(3)(g) Thebond energiesof C-H,C-C,C=C and H-H are 414,347,615 and 435 kJ mol^(-1) respectively

Calculate the enthalpy of the following reaction : H_(2)C = CH_(2)(g)

1.	Calculate the enthalpy of the following reaction : H_(2)C = CH_(2)(g) + H_(2)(g) rarr H_(3)C - CH_(3)(g) Thebond energiesof C-H,C-C,C=C and H-H are 414,347,615 and 435 kJ mol^(-1) respectively
Answer» ANSWER :`-125kJ MOL^(-1)`
