`N_2O_4` at an initial pressure of 2 atm and 300K dissociates to an extent of 20% at the same temperature by the time equilibrium is established. `K_p` for the reaction `2NO_2 harr N_2O_4` is

A

0.4

B

0.8

C

2.5

D

1.6

Text Solution

Verified by Experts

The correct Answer is:
C

`K_(P)=(0.8 xx 0.8)/(1.6)=0.4`
`:. K_(P)` for `2NO_(2) harr N_(2)O_(4)=2.5`

Mass action ratio or reaction quotient Q for a reaction can be calculated using the law of mass action A(g)+B(g) harr C(g) + D(g) Q=([C][D])/([A][B]) . The value of Q decides whether the reaction is at equilibrium or not. At equilibrium, Q = K. For non equilibrium process, Q ne K . When Q gt K , reaction will favour backward direction and when Q lt K , it will favour forward direction.
