Explanation / Answer

a)

on reactant side CH3CH2-H bond is broken and on product side H-Cl bond is formed

delta H = 423 – 431

        = -8 KJ/mol

Answer: -8 KJ/mol

b)

since sign of delta H is negative, it is exothermic reaction

c)

since it is exothermic reaction , it is likely to produce spontaneously
