Figure shows a manometer, one arm is connected with a bulb containing `NH_(3)` and other arm containing `N_(2)H_(4)` both at initial pressure of 1 atm. Initially both arms of manometer contains liquid at same level, what will be difference in level of arms, when 50% `NH_(3)(g)` and 75% `N_(2)H_(4)(g)` dissociates according to the given reaction. Assume temperature remains constant?

`2NH_(3)(g)rarrN_(2)(g)+3H_(2)(g)`
`N_(2)H_(4)(g)rarrN_(2)(g)+2H_(2)(g)`

Options

A. 76 cm if liquid having density 13.6 g/mL is used
B. 38 cm if liquid having density 27.2 g/mL is used
C. 152 cm if liquid having density 6.8g/mL is used
D. 304 cm if liquid having density 3.4g/mL is used
