Given the thermochemical data, determine the enthalpy change for each of the following:

                                         A + B → 2C                 ΔH1 = 600 kJ/mol

                                         2C + D → 2E              ΔH1 = 210 kJ/mol

(a).  4E → 4C + 2D

(b).   A + B + D → 2E

(c).   C → ½ A + ½ B

(d.)    2C + 2E → 2A + 2B + D

(e.)   E → ½ A + ½ B + ½ D
