Answer
A) 163 kPa
B) 448.8 kPa
Work Step by Step
A) Compute the number of moles of nitrogen monoxide beginning with the limiting reactant.
B) Find moles of NH3 and O2 by dividing given mass by molar mass.
2 mol NO is produced because of limiting reactant. Now use the Ideal Gas Law to find pressure. Convert atm to pKa if you want.
Find partial pressures of the rest of the reactants and products.
Find pressure of reactants.
Find total pressure by adding all the partial pressures.
