The reaction of hydrogen sulfide(g) with oxygen(g) to form water(l) and sulfur dioxide(g) proceeds as follows: 2H2S(g) 3O2(g)2H2
Aleks [24]

Answer: The value of \Delta H is 1118 .

Explanation:

To calculate the number of moles,  we use the equation:

\text{Moles of solute}=\frac{\text{given mass}}{\text{molar mass}}    

\text{Moles of} H_2S}=\frac{9.82g}{34.1g/mol}=0.288mol    

The balanced chemical reaction is:

2H_2S(g)+3O_2(g)\rightarrow 2H_2O(l)+2SO_2(g)

Given :

Energy released when 0.288 mole of H_2S is reacted =  161 kJ

Thus Energy released when 2 moles of H_2S is reacted = \frac{161}{0.288}\times 2=1118kJ

Thus the value of \Delta H is 1118.
