At equilibrium for the reaction A ₂(g)+ B ₂(g) 2 AB (g) the concentrations of A ₂, ~B ₂ and AB respectively are 1.5 10⁻³ M , 2.1 10⁻³ M and 1.4 10⁻³ M in a sealed vessel at 800 K . What will be K _ p for the decomposition of AB at same temperature?

Step-by-step solution

aligned & A ₂( ~g )+ B ₂( ~g ) 2 AB ( ~g ) & K _ c = [ AB ]^2 [ ~A ₂ ] [ B ₂ ] & K _ c = 1.4 10⁻³ 1.4 10⁻³ 1.5 10⁻³ 2.1 10⁻³ & ~K _ c =0.622 & ~K _ p = K _ c x ( RT )^ n & n =0 & ~K _ p = K _ c =0.622 aligned aligned K _ p for the decomposition of AB ( ~K ^ ) & = 1 ~K _ p & = 1 0.622 ~K ^ & =1.60 aligned
