$S\:+\:O_{2}$  →  $SO_{2}$    Δ $H=-298.2\:kJ$

$SO_{2}\:+\:\frac{1}{2} O_{2}$ → $SO_{3}$ Δ $H=-98.7\:kJ$

$SO_{3}\:+\:H_{2}O$  →  $H_{2}SO_{4}$ Δ $H=130.2\:kJ$

$H_{2}\:+\:\frac{1}{2} O_{2}$ →$H_{2}O$ Δ $H=-287.3\:kJ$

Δ  $H=-(298.2\:+\:98.7\:+\:130.2\:+\:287.3)=-814.4\:kJ\:mol^{-1}$

Answer 2

Answer:

Explanation:

S\:+\:O_{2}  →  SO_{2}    Δ H=-298.2\:kJ

SO_{2}\:+\:\frac{1}{2} O_{2} → SO_{3} Δ H=-98.7\:kJ

SO_{3}\:+\:H_{2}O  →  H_{2}SO_{4} Δ H=130.2\:kJ

H_{2}\:+\:\frac{1}{2} O_{2} →H_{2}O Δ H=-287.3\:kJ

The\:Formation\:of\:H_{2} SO_{4}\:i.e.

H_{2}\:+\:S\:+\:2O_{2}  → H_{2} SO_{4}\:can\:be\:calculated\:by\:adding\:the\:above\:four\:equations

Δ  H=-(298.2\:+\:98.7\:+\:130.2\:+\:287.3)=-814.4\:kJ\:mol^{-1}
