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 answer to 2 significant figures and include units. PartB: If 0.25 mol of Br2 and 0.55 mol of Cl2 are introduced into a 3.0 L container at 400K, 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? express answer to 2 significant figures and include the appropriate units

For the equilibrium Br2(g)+Cl2(g)2BrCl(g)at400K,Kc=7.0
