The enthalpies for the following reactions `(DeltaH^(Theta))` at `25^(@)C` are given below. a. `(1)/(2)H_(2)(g) +(1)/(2)O_(2)(g) rarr OH(g)` `DeltaH = 10.06 kcal` b. `H_(2)(g) rarr 2H(g), DeltaH = 104.18 kcal` c. `O_(2)(g) rarr 2O(g), DeltaH = 118.32 kcal` Calculate the `O-H` bond energy in the hydroxyl radical. |

Answer» Required equation is `H(g)+O(g)toO-H(g)`, `DeltaH=?` Given, `(1)/(2)H_(2)(g)+(1)/(2)O_(2)(g)toOH(g)," "DeltaH=+10.06kcal` `H(g)to(1)/(2)H_(2)(g)," "DeltaH=-52.09kcal` `O(g)to(1)/(2)O_(2)(g)," "DeltaH=-59.16kcal` Adding, `H(g)+O(g)to OH(g)," "DeltaH=-101.19kcal` |
