At 25°C, Kp = 2.910−3 for the following reaction.
NH4OCONH2(s) 2 NH3(g) + CO2(g)
In an experiment carried out at 25°C, a certain amount of NH4OCONH2 is placed in an evacuated rigid container and allowed to come to equilibrium. Calculate the total pressure in the container at equilibrium.

    I can't tell what the value of Kp is. I will assume you meant it to be 2.91E-3. BTW, you need to learn where the arrow key is too. The arrow tells us where the reactants stop and the products begin.

    ......NH4OCONH2(s) ==> 2NH3 + CO2
    I.......solid...........0.......0
    C.......solid...........2x.......x
    E.......solid...........2x......x

    Kp = p^2NH3*pCO2
    Kp = (2x)^2(x)

    Solve for x, 2x, and add the two pressures to find the total pressure.
