Question

At 550 K, the K c ​ for the following reaction is 1 0 4 m o l − 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?

TestHub · Accepted Answer

Let K c ​ = [ X ] [ Y ] [ Z ] ​ . [ X ] = 2 1 ​ [ Y ] = 2 1 ​ [ Z ] = a let [ Z ] = 2 a , [ Y ] = 2 a , [ X ] = a 1 0 4 = a × 2 a 2 a ​ a = 1 0 − 4 [ Z ] = 2 a = 2 × 1 0 − 4 m o l L − 1
