11 moles of N_(2) and 12 moles of H_(2) mixture reacted in 20 litre vessel at 800 K. After equilibrium was reached, 6 mole of H_(2) was present. 3.58 litre of liquid water is injected in equibrium mixture and resultant gaseous mixture suddenly cooled to 300K. What is the final pressure of gaseous mixture? Neglect vapour pressure of liquid solution. Assume (i) all NH_(3) dissolved in water (ii) no change in volume of liquid (iii) At 300 K no reaction takes place between N_(2) and H_(2)
