The figure shows initial conditions of a uniform cylinder with frictionless pistons A and B held in shown position by mechanical stoppers.

If the mechanical stoppers holding piston A and B as shown in figure are removed and in the mean time `N_(2)O_(4) and O_(3)` gases separately undergo following reaction completely [Assume that temperature remains constant]
`N_(2)O_(4) rarr 2NO_(2)`
`2O_(3) rarr 3O_(2)`
Which statement is incorrect after attaining final equilibrium state?

Options

A. Position of piston A is 45 cm from left end
B. Position of piston B is 60 cm from left end
C. Total moles of gases in all compartments is 18.
D. Position 'B' final and initial position are different

Answer

d
