Answer to Question #293959 in General Chemistry for jjj

Question

1.     Find the enthalpy change for the reaction       (5 points)

         CS_{2 (l)}  + 3 O_{2 (g)} → CO_{2 (g)}  + 2 SO_2(g)      

When:   C(s) + O_2(g) → CO_{2 (g)}             

                       S_(s) + O_{2 (g)} → SO_2(g)              

               C_(s) + 2S(s) → CS_2(l)       

Answer 1

$\Delta{H}_{reaction}=\sum{\Delta{H_{products}-\sum\Delta{H}_{reactants}}}=-393.5+2(-296.8)-87.9=-1075kJ/mol$

Answer: -1075 kJ/mol
