What is the equilibrium equation for the reaction:
NH4NO3(s) ⇌ N2O(g) + 2 H2O(g)?
. If Kc is the equilibrium constant for a forward reaction, 2 A⇌ B, what is Kc' for the reaction 4 A⇌ 2B?
Which of the following statements is false regarding the equilibrium constant, Kc?
A) Kc for a reaction at a particular temperature always has the same value.
B) Kc for the reverse reaction is the negative of Kc for the forward reaction.
C) The numerical value of Kc depends on the form of the balanced equation.
D) When quoting Kc it is customary to omit units.
write the expression for the equilibrium constant Kc and state their units.
a. 2NO2 ⇌ N2O4
b. N2+3H2 ⇌ 2NH3
c. CH3CH2CO2H(l) + CH3CH2OH(l) ↔ CH3CH2CO2CH2CH3(l) + H2O(l)
6. Nitric oxide reacts with oxygen to form nitrogen dioxide:
2 NO(g) + O2(g) ⇌ 2 NO2(g)
What is Kc' for the reverse reaction if the equilibrium concentration of NO is 0.300 M, O2 is 0.200 M, and NO2 is 0.530 M at 25°C?
8. What is the value for Kc for the following reaction:
PbCl2(s) ⇌ Pb2+(aq) + 2 Cl-(aq),
if PbCl2(s) = 1.50 grams, [Pb2+] = 1.6 × 10-2 M and [Cl-] = 3.2 × 10-2 M at equilibrium? (The molar mass of PbCl2(s) is 278 g/mol and its density is 5.85 g/cm3.)

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
