Consider the reaction:
2 CO(g) + O₂(g) 2 CO₂(g).
The reaction is allowed to reach equilibrium in a sealed vessel. According to Le
Chatelier's principle, what will happen to the equilibrium, if the volume of the vessel
is decreased while the temperature is kept constant?
(A) The equilibrium constant will decrease and the reaction will shift to the left.
(B) The equilibrium constant will be unchanged, but the reaction will shift to the
left.
(C) The equilibrium constant will be unchanged, but the reaction will shift to the
right.
(D) The equilibrium constant will increase and the reaction will shift to the right.
(E) The equilibrium concentrations will not be affected.
Using the law of mass action, write the equilibrium
expression for each of the following reactions.
(a) 3 CH½(g) + 3 H½(g) 2 CI112(€)
(b) CO2(g) + C(s) 2 2 CO(g)
(c) CF4(g) + 2 H;O(€) = CO2(g) + 4 HF(g)
(d) K2NİF6(s) + TIF4(s) 2 K,TiF,(s) + NIF2(s) + F2(g)
The equilibrium constant (KP) for the formation of the air pollutant nitric oxide (NO) in an automobile engine at 537°C is 4.5 × 10−11.
N2(g) + O2(g) ⇌ 2NO(g)
(a) Calculate the partial pressure of NO under these conditions if the partial pressures of nitrogen and oxygen are 3.00 and 0.012 atm, respectively.
(b) Repeat the calculation for atmospheric conditions in which the partial pressures of nitrogen and oxygen are 0.78 and 0.21 atm, and the temperature is 25°C. (The KP for the reaction is 4.0 × 10−31 at this temperature.)
