In the reaction below, 8.34 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) <=> 2 HBr(g) Given that Kc = 86.7, calculate the equilibrium pressure of Br2.
a 6.0-g sample of [Ni(H2O)6]Cl2 is dissolved in aqueous solution. If an excess of ethylenediamine (en) is added to the solution, solid [Ni(en)3]Cl2*2H2O forms. What is the theoretical yield of product from the reaction?
A sample of ammonia gas was allowed to come to equilibrium at 400 K.2NH3(g) ↔ N2(g) + 3H2(g) At equilibrium, it was found that the concentration of H2 was 0.0584 M, the concentration of N2 was 0.0195 M, and the concentration of NH3 was 0.430 M.
