In an artificial game company they want to improve gunpowder for this they raise the following reactions:

Nitrogen with its ultimate valence reacts with oxygen to produce an oxide acid, then it reacts with water to produce an oxacid acid, this reacts with potassium hydroxide and as a product it has a neutral salt plus water. The reaction conditions are:

The temperature is 500K, the volume of the reaction is 0.45 liters, the grams of each reactant is 20 grams of input, and the pressure is 6 atm. When equilibrium is established, the moles of the hydroxide are equal to those of the salt.

a) Calculate the equilibrium concentrations, Ke, Kp b) The partial pressures of each compound present in the reaction

Pls, dont use other's people answers since they are wrong.
