The following acid-base reaction occurs spontaneously in the gas phase at 25.0°C: NH₃(g) + HCl(g) ⇌ NH₄Cl(s) Calculate the equilibrium constant for this reaction at 287.15 K.
NH3 (g) =-17
HCl (g)=-95
NH4Cl (S)=-203
Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NOCI (g) = 2NO (g) + Cl2 (g) AGº =41. kJ
Now suppose a reaction vessel is filled with 7.85 atm of nitrosyl chloride (NOCI) and 5.15 atm of chlorine (C12) at 834. °C. Answer the following questions
about this system:
rise
Under these conditions, will the pressure of C₁₂ tend to rise or fall?
☐ x10
fall
Is it possible to reverse this tendency by adding NO?
In other words, if you said the pressure of C12 will tend to rise, can that be
changed to a tendency to fall by adding NO? Similarly, if you said the
pressure of C₁₂ will tend to fall, can that be changed to a tendency to rise
by adding NO?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO needed to reverse it.
