For the reaction ${H_2}_{(g)} + \frac{1}{2}{O_2}_{(g)} \to {H_2}O(\ell)$,given $\Delta C_P = 7.63 \, cal/deg$ and $\Delta H_{25\,^{\circ}C} = 68.3 \, Kcal$,find the value of $\Delta H$ at $100\,^{\circ}C$ (in $Kcal$).
- A$7.63 \times 10^{-3} \times (373 - 298) - 68.3$
- B$7.63 \times 10^{-3} \times (373 - 298) + 68.3$
- C$7.63 \times (373 - 298) - 68.3$
- D$7.63 \times (373 - 298) + 68.3$
