Question

Consider the following reaction where Kc = 6.50×10-3 at 298 K:

2 NOBr (g) 2 NO (g) + Br2 (g)

A reaction mixture was found to contain 8.07×10-2 moles of NOBr (g), 4.06×10-2 moles of NO (g), and 4.46×10-2 moles of Br2 (g), in a 1.00 liter container.

Indicate True (T) or False (F) for each of the following:

1. In order to reach equilibrium NOBr(g) must be consumed .

2. In order to reach equilibrium Kc must decrease .

3. In order to reach equilibrium NO must be consumed .

4. Qc is less than Kc. 5. The reaction is at equilibrium. No further reaction will occur.
