Homework,
week 10 Answer key
1. Determine
D K at
298 K for each
of the following reactions:_{P}
a) N
b) H
c) 3 H 2. The
synthesis
of ammonia is given by the formula
N a) If you begin the reaction with _{2(g)} and 3n moles of H_{0}_{2(g)}, find an exact expression
for z.
Use this expression to discuss how _{eq}z
varies with _{eq}P and
relate your conclusions to Le
Chatelier’s principle. 3. Sufuryl
chloride,
SO
SO D _{2})
= -371.3 kJ/mol, DG (SO^{0}_{f}_{2}) = -300.2 kJ/mol.a) Determine
the
equilibrium concentrations of each species if the system initially
contains
1 mole of SO b) Determine the equilibrium concentrations of
each species
if the system initially contains 1 mole of SO c) Describe any differences according to Le Chatelier’s principle. 4. The
water-gas
shift reaction is an important industrial source of pure H
CO(g)
+ H What would happen to the equilibrium concentration of each species if you increase the total pressure of the system by a factor of 100? 5. Until
recently,
values of K
values at 1 atm to 1 bar._{P}6. Under
certain
conditions, water vapor dissociates into H |
