When `N_(2)O_(5)` is heated at certain temperature, it dissociates as `N_(2)O_(5)(g)hArrN_(2)O_(3)(g)+O_(2)(g),K_(c)=2.5` At the same time `N_(2)O_(3)` also decomposes as :
`N_(2)O_(3)(g)hArrN_(2))(g)+O_(2)(g).` "If initially" `4.0` moles of `N_(2)O_(5)` "are taken in" `1.0` litre flask and alowed to dissociate. Concentration of `O_(2)` at equilibrium is `2.5` M. "Equilibrium concentratio of " `N_(2)O_(5)` is :

A

1.0 M

B

1.5 M

C

2.166 M

When N_(2)O_(5) is heated at certain temperature, it dissociates as N_(2)O_(5)(g)hArrN_(2)O_(3)(g)+O_(2)(g),K_(c)=2.5 At the same time N_(2)O_(3) also decomposes as : N_(2)O_(3)(g)hArrN_(2)O(g)+O_(2)(g). "If initially" 4.0 moles of N_(2)O_(5) "are taken in" 1.0 litre flask and alowed to dissociate. Concentration of O_(2) at equilibrium is 2.5 M. "Equilibrium concentratio of " N_(2)O_(5) is :

For the first order reaction 2N_(2)O_(5)(g) rarr 4NO_(2)(g) + O_(2)(g)

For reaction 2NO(g)hArr N_(2)(g)+O_(2)(g) degree of dissociation of N_(2) and O_(2) is x. Initially 1 mole of NO is taken then number of moles of O_(2) at equilibrium is

For a reaction, 2N_(2)O_(5)(g) to 4NO_(2)(g) + O_(2)(g) rate of reaction is:

When N_(2)O_(5)(g) is heated it dissociates to give N_(2)O_(3) and O_(2) . K_(c) for N_(2)O_(5)rarr N_(2)O_(3)+O_(2) is 7.75 and K_(c) for N_(2)O_(3)rarr N_(2)O+O_(2) is 4.0 mol L^(-1) . (both K_(c) are at same temperature) 4 mol N_(2)O_(5) in 1.0L vessel is kept at a certain temperature. the concentration of O_(2) was 4.5 mol L^(-1) . Find the concentration of N_(2)O_(5), N_(2)O_(3) , and N_(2)O at equilibrium.
