Given the bond energies (in kJ/mol) of the following bonds: F–F (155), F–Cl (193), and Cl–Cl (243), estimate the molar enthalpy of formation of ClF(g), that is find ∆H for the following reaction
½Cl2(g) + ½F2(g) → ClF(g)
A. 209 kJ/mol
B. -50. kJ/mol
C. –8 kJ/mol
D. –209 kJ/mol
E. 8 kJ/mol
Homework Answers
∆H = BE (reactant) - BE(product)
= 1/2*BE(Cl-Cl) + 1/2*BE(F-F) - BE(Cl-F)
= 1/2 * 243 + 1/2 * 155 - 193
= 6 KJ/mol
Option E is closest
