Using the bond energy data from your text (or the internet), determine (show calculations for) the approximate enthalpy change , ∆H, for each of the following reactions:
(a) Cl2 (g) + 3F2 (g) ⟶ 2ClF3 (g)
(b) H2C=CH2 (g) + H2 (g) ⟶ H3CCH3 (g)
Calculate the enthalpy change for the following reactions using the bond enthalpy given below. (Bond enthalpy/kJ : H−H = 436, C−H = 413, C=O = 799, O=O = 495, O−H = 463)
(a) H2(g) + 1⁄2O2(g) → H2O(g)
