(\Delta H) for the reaction, (OF\_2 + H\_2O \to O\_2 + 2HF)... | Chemistry | SolveeIt

$\Delta H$ for the reaction, $OF_2 + H_2O \to O_2 + 2HF$ $(B.E.$ of $O ?

$- 222\, kcal$

$- 88\, kcal$

$- 111\, kcal$

$- 79\, kcal$

Answer

$- 79\, kcal$

Explanation

$\Delta H = \Sigma\,B.E._{R} - \Sigma\,B.E._{P}$ $= \left(2 \times 44 + 2 \times 111\right) - \left(119 + 2 \times 135\right)$ $= - 79 \,kcal$
