The reaction of hydrogen sulfide(g) with oxygen(g) to form water(l) and sulfur dioxide(g) proceeds as follows: 2H2S(g) 3O2(g)2H2O(l) 2SO2(g) When 9.82 g H2S(g) reacts with sufficient O2(g), 161 kJ is evolved. Calculate the value of rH for the chemical equation given. kJ/mol

The value of is 1118 .

Explanation:

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

The balanced chemical reaction is:

Given :

Energy released when 0.288 mole of is reacted =  161 kJ

Thus Energy released when 2 moles of is reacted =

Thus the value of is 1118.
