Chemistry

Be sure to answer all parts.

At 430

°

C, the equilibrium constant (KP) for thereaction

2NO(g)

+ O2(g) ⇆ 2NO2(g)

is 1.5

×

105. In one experiment, the initial pressures of NO,O2, and NO2 are  7.4

×

10−3 atm, 4.2

×

10−2 atm, and

0.20 atm,

respectively. Calculate QP and predict thedirection that the net reaction will shift to reachequilibrium.

What is QP for the experiment?


In which direction will the system proceed to reach equilibrium?
  

The reaction will proceed to the right.

  

The reaction will proceed to the left.

  

The reaction is at equilibrium.
