What is the total energy change for the following reaction: CO + H2O -> CO2 + H2?

Given:
C-O bond: 358 kJ/mol
H-O bond: 463 kJ/mol
H-H bond: 436 kJ/mol

A. +132 kJ/mol
B. +1152 kJ/mol
C. +27 kJ/mol
D. -541 kJ/mol

Respuesta :

1)Delta H=(Delta H of reactants)-(Delta H of products)

2)And we know CO have 3 bond CO and CO2 have 2 bond that each of them are 2 bond, please see the picture!

so lets answer it:

[tex](3 \times 358) + (2 \times 463) - (4 \times 358) - 436 = 132[/tex]
