At 550 ~K , the K_c for the following reaction is 10^4 ~mol ⁻¹ ~L X(g)+Y(g) Z(g) At equilibrium, it was observed that [X]= 1 2 [Y]= 1 2 [Z] What is the value of [Z] (in mol L ⁻¹ ) at equilibrium?

Question

Quantrex Academy · Accepted Answer

Correct answer: A. 2 10⁻⁴

aligned & X(g)+Y(g) Z(g) & K_c= [Z] [X][Y] or 10^4= [Z] [X][Y] & [Z]=10^4[X][Y]=10^4 1 2 [Z][Z] & (Given, [X]= 1 3 [Y]= 1 2 [Z] ) & [Z]=2 10⁻⁴ ~mol ~L ⁻¹ & aligned
