Question

At 550 K , the K c ​ for the following reaction is 1 0 4 mol − 1 L . X(g) + Y(g) ⇌ Z(g) At equilibrium, it was observed that [ X ] = 2 1 ​ [ Y ] = 2 1 ​ [ Z ] . What is the value of [ Z ] at equilibrium?

K C ​ = [ X ] [ Y ] ] [ Z ] ​ [ X ] = 2 1 ​ [ Y ] = 2 1 ​ [ Z ] = a ( l e t ) [ Z ] = 2 a , [ Y ] = 2 a , [ X ] = a . Therefore, 1 0 4 = a × 2 a 2 a ​ . So, a = 1 0 − 4 . Thus, [ Z ] = 2 a = 2 × 1 0 − 4 m o l L − 1 .
