A handbook gives the heat of combustion of liquid carbon disulfide as -3.42 kcal/g of the liquid. Write the equation representing the combustion of 1 mol of carbon disufide and the accompanying ΔH value. (hint: the sulfur containing combustion product is sulfur dioxide).

Answer 1

-3.42 kcal/g x (76g/mol) = approx -260 kcal/mol
CS2 + 3O2 ==> CO2 + 2SO2 + 260 kcal/mol
