Question

For the equilibrium
Br2(g)+Cl2(g)⇌2BrCl(g)
at 400 K, Kc = 7.0.

Part A

If 0.25 mol of Br2 and 0.55 mol of Cl2 are introduced into a 3.0-L container at 400 K, what will be the equilibrium concentration of Br2?

Express your answer to two significant figures and include the appropriate units.

Part B

If 0.25 mol of Br2 and 0.55 mol of Cl2 are introduced into a 3.0-L container at 400 K, what will be the equilibrium concentration of Cl2?

Part C

If 0.25 mol of Br2 and 0.55 mol of Cl2 are introduced into a 3.0-L container at 400 K, what will be the equilibrium concentration of BrCl?
