Explanation / Answer

For the given reaction,

(a) Using bond enthalpy

dHrxn = dH(reactants) - dH(products)

           = (413 + 146) - (358 + 463)

           = -262 kJ/mol

(b) It is an exothermic reaction as dH is -ve.

(c) Reaction is spontaneous

---

For the given reaction,

(a)

dHrxn = dH(reactants) - dH(products)

           = 413 - 565

           = -152 kJ/mol

(b) It is an exothermic reaction as dH is -ve.

(c) Reaction is spontaneous

For the given reaction,

(a)

dHrxn = dH(reactants) - dH(products)

           = 413 - 463

           = -50 kJ/mol

(b) It is an exothermic reaction as dH is -ve.

(c) Reaction is spontaneous
