In order to Calculate ∆Hrxn for the given equation we have:
∆H° of the following reaction H₂O(g) + CH₂ = CH₂→ CH₃CH₂OH is
-464kJ/mol.
Bond energies in kJ/mol
H—O = 463
C=C = 145
C—O = 1072kJ/mol.
Now, the given reaction is
H₂(g) + I₂(g) → 2HI(g)
Here, 1 mol of H₂ and 1 mole of I₂ breaks to form 2 moles of HI.
Therefore,
We know that,
∆Hrxn = B. E(O—H) + B. E(C=C) - B. E(C—O)
= 463 + 145 - 1072
= 436+ 151 - 590
∆Hrxn = -464kJ/mol.
What is bond energy?
The amount of energy needed to disassemble a mole of molecules into their individual atoms is referred to as bond energy (E). It gauges the sturdiness of a chemical connection. Bond strength or bond enthalpy (H) are other names for bond energy.
Bond energy, also known as the mean bond enthalpy or average bond enthalpy, is the term used to describe the strength of a chemical bond in chemistry. According to IUPAC, bond energy is the average bond-dissociation energy in the gas phase for all bonds of the same type within a single chemical species.
The average of all bond-dissociation energies of a single type of bond in a given molecule is known as the bond energy (BE).
