1. For the reaction N2 + O2 &#8594; 2NO, Kc = 4.08 x 10-4 at 2000K. What is Kc at this same temperature for the reaction, NO &#8594; 1/2 O2 + 1/2 N2

For the reaction:
N2 + O2 &#8594; 2NO
We have

NO &#8594; 1/2 O2 + 1/2 N2

For the above reaction we have:

2. What is the total pressure of the gases above the carbon for the reaction C + CO2 &#8594; 2CO when the pressure of CO is ten times the pressure of CO2? The equilibrium constant, Kp = 63.

C + CO2 &#8594; 2CO
We are given pCO = 10pCO2
We can write the Kp as:
= 63
Thus pCO2 = 63/100 = 0.63 (pressure unit)
The total gas pressure for the reaction is = pCO2 + pCO = 0.63 + 6.3 = 6.93 (pressure unit)

3. Calculate the value of Kc for the reaction Ag+(aq) + Cl-(aq) &#8594; AgCl(s) if the concentrations at equilibrium are [Ag+] = 10-8M, [Cl-] = 0.01M.

Ag+(aq) + Cl-(aq) &#8594; AgCl(s)
