A mixture of NH3 g and N H4 g is placed in a sealed container at 300K The total pressure is 0 55 atm The container is heated to 1200K at which both gases decompose completely according to the equation 2NH3 g N2 g 3H g and N H g N g 2H g After complete decomposition the total 4 pressure at 1200K is found to be 5 5 atm Find the moles of N H4 in the original mixture A 30 B 25 C 40 D 75
