Question
We want to calculate the heat of dissolution
of sulfuric acid in water. There is a calorimeter
with Cequipo = 4.5 Kcal / ° Cand with 3 liters
of water in the jacket. Put in the reaction
chamber of the calorimeter 4 liters of water
and 2 liters of 2 Normal sulfuric acid and
density 1.2 g / ml. The cp of the resulting
solution is 1.2 cal / g°C (water + sulfuric acid).
It is known that 35% of the heat produced by
the solution goes to the environment. The
total system undergoes an increase of 5° C.
Calculate the heat of dissolution of sulfuric
acid in water in Kj / mol of sulfuric acid.
a. +200.44 Kj/mol
b. -204.44 Kj/mol
C. -244.05 Kj/mol
d. -255.05 Kj/mol
