A vessel originally contained 0.050 mol iodine monobromide (IBr), 0.0014 mol I 2

Question

A vessel originally contained 0.050 mol iodine monobromide (IBr), 0.0014 mol I2, and 0.0058 mol Br2.

The equilibrium constant Kc for this reaction is 1.2 ? 102 at 150?C. What is the direction (forward or reverse) needed to attain equilibrium at 150?C?

What is the value of Q?

A vessel originally contained 0.050 mol iodine monobromide (IBr), 0.0014 mol I2, and 0.0058 mol Br2. I2(g) + Br2(g) rightleftharpoons 2 lBr(g) The equilibrium constant Kc for this reaction is 1.2 ? 102 at 150½C. What is the direction (forward or reverse) needed to attain equilibrium at 150½C? What is the value of Q?

Explanation / Answer

the value of Q is 143 J
