Answer to Question #112218 in Physical Chemistry for kumbiraiishe

Question

Calculate the percentage change in the equilibrium constant Kx of the reaction
H2CO(g) CO(g)+H2(g) when the total pressure increased from 1 bar to 2 bar at constant pressure.

Answer 1

$$K_x=\frac{[CO][H_2]}{H_2CO}$$

= so Kx will be increased by 4 times if pressure is changed from 1.0 bar to 2.0 bar so percentage change will be 300%
