For the reaction below:
a. Determine whether the reaction is energetically favorable at
room temperature. Assume that ΔS=O. Calculate the gas phase
enthalpy change using bond dissociation enthalpies at 25°C from the
table below. Hint: Be aware that the bond energy for the C-H bond
varies considerably and may change during the reaction; therefore,
you will find several entries for C-H bonds in the table. Include
the algebraic sign and specify units, e.g. -45 kJ/mol. Calculate to
the nearest single...
