Question

In the chemical reaction where N2O4 (g) is converted to 2NO2 (g), if 0.5 M N2O4 and 0.15 M NO2 are in the vessel, is the reaction at equilibrium? If, not, which direction would the reaction proceed? ( Kc = 4.4 x 1p^-3) N2O4 (g) = 2NO2 (g)

Answer 1

A. No, Q= 0.18 so the reaction should proceed in the forward direction
B. No, Q= 9.0 x 10^-2 so the reaction should proceed in the reverse direction
C. No, Q= 4.5 x 10^-2 so the reaction should proceed in the reverse direction
D. Yes, the reaction is at equilibrium

Answer 2

Write the Kc expression for the given equilibrium using the concentrations given and see if the obtained Kc value is equal to the Kc value given in the question

Answer 3

Write the Kc expression for the given equilibrium using the concentrations given and see if the obtained Kc value is equal to the Kc value given in the question \[Kc = \frac{ [NO2]^{2} }{ [N2O4] }\]
\[Kc = \frac{ [0.15]^{2} }{ 0.5 }\]

Answer 4

I got 0.045 So C is the answer ? @Rushwr
