To determine the value of KP, the equation relating KP and KC needs to be used. The equation is:
KP = KC(RT)^(Δn)
Where:
KP is the equilibrium constant in terms of partial pressures
KC is the equilibrium constant in terms of concentrations
R is the ideal gas constant
T is the temperature in Kelvin
Δn is the difference in the number of moles of gas between the products and reactants
In this reaction, the balanced equation is:
N2(g) + O2(g) ⇌ 2NO(g)
The reaction involves 2 moles of gas on the left side (N2 and O2) and 2 moles of gas on the right side (2NO). Therefore, Δn = 2 - 2 = 0.
Given that KC = 2 x 10^-3, we can use the equation to solve for KP:
KP = KC(RT)^Δn
Since Δn = 0, the equation simplifies to:
KP = KC
Substituting the given value of KC, we get:
KP = 2 x 10^-3
Therefore, the correct answer is option 'D', which is 2 x 10^-3.

As we know that KC = KP(RT)Δng, here Δng = moles of products – moles of reactants which are in gaseous state only = 2 – (1+1) = 0. So KC = KP(RT)0, KC = KP(1) = KP; KC = KP, therefore KP is same as KC and KP is 2 x 10-3.
