Calculate the heat of reaction for the following reaction $S O_{2} + \frac{1}{2} O_{2} \to S O_{3}$ . Given the values of heat of formation of $S O_{2}$ and $S O_{3}$ are $- 298.2$ $k J$ and $- 98.2 k J$ .

Options:

Answer:

Solution:

$S + O_{2} \to S O_{2} Δ H = - 298.2 k J$ ...........(i)
$S O_{2} + \frac{1}{2} O_{2} \to S O_{3} Δ H = - 98.2 k J$ .........(ii)
eq. $(i) - (i i)$ and find the required result.
