Gaseous StateHard

Question

N2 + 3H2 → 2NH3. 1 mol N2 and 4 mol H2 are taken in 15 L flask at 27oC. After complete conversion of N2 into NH3, 5 L of H2O is added. Pressure set up in the flask is :

Options

A.atm
B.atm
C.atm
D.atm

Solution

                  N2        +     3H2     →   2NH3
t = 0       1 mole          4 mole                  0
t = tfinal      0              1 mole              2 mole
NH3 will absorb by water and volume will be 15 - 5 = 10 L
P = atm
