Transcribed Image Text:2. Sulfuryl chloride (SO,Cl,) decomposes to give sulfur dioxide and
and diatomic chlorine (all gases).
a. Calculate the enthalpy of formation for this reaction using
Hess's Law. The one value you can't find easily is that of
SO,Cl, – it's Hf=-391.4 kJ/mol.
b. 243 grams of SO,Cl, are placed in a 2.5 L flask and the
temperature is brought to 375 deg. C. The concentration of
Cl, is measured and reaches a constant value of 0.159M.
What is the equilibrium constant for this reaction?
c. Which way would the equilibrium shift if the temperature was
raised?
d. Write 3 brief sentences
one that gives information on what
the value of DH says about the reaction, one on what the value
of K says about the reaction and a third sentence about express
if the values for part a and part b are corroborative or
completely separate values that give us completely different
information.
5 grams of Cl, are added to the reaction in part b after
equilibrium had been established. What are the new
equilibrium concentrations once equilibrium has been
reestablished?
