Problem 14SAQ

Use bond energies to determine  for the reaction between ethanol and hydrogen chloride.

a) -1549 kJ

b) 1549 kJ

c) -12 kJ

d) 12 kJ

Step-by-Step Solution:

Solution 14SAQ We want to demonstrate the righ option is c) H =rxn2 KJ Step 1 of 2 The reaction consists in breaking C-O and H-Cl bonds and in forming C-Cl and H-O bonds. Since H = H’s bonds broken - H’s bonds formed rxn We have to know the H for C-O and H-Cl bonds breaking and H for C-Cl and H-O bonds formation. We know that when bonds break, the process is endothermic (H>0) and when bonds form, the process is exothermic (H<0).
