At T ( K ) , the K _ p for the reaction A ₂ ~B ₆( ~g ) A ₂ ~B ₄( ~g )+ B ₂( ~g ) is 0.04 ~atm . The equilibrium pressure (in atm) of . A ₂ ~B ₆ ) g ) when it is placed in a flask at 4 ~atm pressure and allowed to come to above equilibrium is

Step-by-step solution

A ₂ ~B ₆( ~g ) A ₂ ~B ₄( ~g )+ B ₂( ~g ) aligned & Initial array l p =4 ~atm 0.0 array l Equilibrium =4 array p =4 array p =4 & array l K _ p = P ( A ₂ ~B ₄ ) P ( B ₂ ) P ( A ₂ ~B ₆ ) =0.04 ~atm = (4 )(4 ) 4(1- ) = 4 ^2 1- 4 ^2 =0.1 array aligned Therefore, P ( A ₂ ~B ₆ ) at equilibrium =4(1- ) aligned & =4(1-0.1) & =3.62 aligned
