Mass action rato or reaction quotient Q for a reaction can be calculate using the law of masss 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 an equilibrium process, `Q ne K`  when `Q gt K`, reaction will favour backward direction and when `Q lt K`, it will favour direction.  Answer the following questions:  In a reaction mixture containing `H_(2), N_(2)` and `NH_(3)` at partial pressure of `2` atm, `1` atm and `3` atm respectively, the value of `K_(p)` at `700 K` is `4.00xx10^(-5) atm^(-2)`. In which direction the net reaction will go?  `N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g)`
