Question
Sulfur (2.55 g) was burned in a constant volume calorimeter
with excess O₂(g). The temperature increased from 20.56 °C
to 25.78 °C. The bomb has a heat capacity of 933 J/K, and the
calorimeter contained 858 g of water. (Specific heat capacity of
water is 4.184 J/g. K.) Calculate AU per mole of SO2 formed
for the reaction.
S8 (s) + 8 O₂ (g) → 8 SO₂ (g)
Sulfur burns in oxygen with a bright blue flame to give SO₂ (g).
AU =
kJ/mol SO₂
