n = (sum of stoichiometric coefficients of products) - (sum of stoichiometric coefficients of reactants)
Here, N2O and H2O are present on product side and their stoichiometric coefficients in the balanced reaction are 1 and 2 respectively.
Therefore, sum of stoichiometric coefficients of products = 1+2 = 3
Also, NH4NO3 is present on reactant side and its stoichiometric coefficient is 1.
Therefore, sum of stoichiometric coefficients of reactants = 1
Hence, n = 3-1 = +2.
So, D is the right answer.

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)Δn where R=0.08206 L⋅atm/(K⋅mol), T is the absolute temperature, and Δn is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction N2(g)+3H2(g)⇌2NH3(g) for which Δn=2−(1+3)=−2. A) For the reaction 3A(g)+3B(g)⇌C(g) Kc =...
