Ideal behavior is approached by gases when the conditions of the system are at a low pressure and high temperatures. Therefore, the correct answer is C. At the conditions of lowest temperature highest pressure, gases will deviate from an ideal gas.

He equilibrium constant (KP) is 0.21 at a particular temperature for the reaction:
lorasvet [3.4K]

Explanation:

We will use the following equation,  

     Q_{p} = \frac{(P^{2}_{NO_{2}}{P_{N_{2}O_{4}}

(a) Now, we will calculate the value of Q_{p} as follows.

          Q_{p} = \frac{(0.225)^{2}}{0.134}

                      = 0.377

As, the K_{p} is 0.21 (which is smaller than the value) this means that equilibrium will shift to the left .

(b)   Q_{p} = \frac{(0.086)^{2}}{0.064}

                  = 0.1155

Here, Q_{p} is smaller than k_{p} which means that the equilibrium will shift to the right.

(c)   Q_{p} = \frac{(0.13)^{2}}{0.142}

                   = 0.119

Here, Q_{p} is smaller than k_{p} which means that the equilibrium will shift to the right .

(d)    Q_{p} = \frac{(0.173)^{2}}{0.142}

                  = 0.21  

Since, here the value of Q_{p} comes out to be equal to the given value. Therefore, this reaction is at equilibrium.

(e)  Q_{p} = \frac{(0.151)^{2}}{0.062}

                  = 0.36

Here, Q_{p} is higher than k_{p} the reaction will shift to the left.
