Answered by GPT 3.5
The equilibrium constant (Keq) is calculated by taking the product of the concentrations of the products and raising each concentration to the power of its coefficient in the balanced equation, and then dividing by the product of the concentrations of the reactants raised to the power of their coefficients.

The balanced equation is: N2 (g) + 3 H2 (g) → 2 NH3 (g)

Plugging in the given concentrations, we get:

Keq = ([NH3]^2)/([N2]*[H2]^3)
= (0.325^2)/(0.385*0.75^3)
= 0.650/0.407
= 1.594

Rounding to the appropriate number of significant figures, the answer is 1.59

Therefore, the correct answer is not listed.
