Chemical equilibrium post assessment part q24

Postby Alana Sur 3B » Tue Jan 22, 2019 10:49 pm

Can someone pls explain q24 of the Chemical Equilibrium Part 2 Post Assessment?

Q. The equilibrium constant, KP, for the reaction SO2 (g) + O2 (g) ⇌ SO3 (g) at 700 K is 3 x 104. A mixture of SO2, O2, and SO3, each at 65 bars was introduced into a container at 700 K. Is the reaction at equilibrium? If not, does SO3 tend to form or decompose?

A. At equilibrium.

B. Not at equilibrium, SO3 tends to decompose.

C. Not at equilibrium, SO3 tends to form.

D. It is not possible to tell.

First, you have to calculate Q. Then, compare Q to the K value. If Q<K, the reaction proceeds to products. If Q> K, the reaction favors the left.
