Calculate the enthalpy of reaction for 2CO + O2 → 2CO2. given the following bond energies:
kotegsom [21]

Answer : The enthalpy change for the reaction is 1043 kJ/mol.

Explanation :

The given chemical reaction is:

2CO+O_2\rightarrow 2CO_2

As we know that:

The enthalpy change of reaction = E(bonds broken) - E(bonds formed)

\Delta H=[(2\times B.E_{C\equiv O})+(1\times B.E_{O\equiv O})]-[2\times B.E_{C=O}]

Given:

B.E_{C\equiv O} = 1074 kJ/mol

B.E_{O\equiv O} = 499 kJ/mol

B.E_{C=O} = 802 kJ/mol

Now put all the given values in the above expression, we get:

\Delta H=[(2\times 1074kJ/mol)+(1\times 499kJ/mol)]-[2\times 802kJ/mol]

\Delta H=1043kJ/mol

Therefore, the enthalpy change for the reaction is 1043 kJ/mol.
