Question

4. The equilibrium constant values for a number of reactions are listed below. Indicate whether the products or reactants are favored. Reaction Which side is favored? NH3(aq) + H2O(l) 5 NH4+ (aq) + OH(aq) K = 5.0 x 1012 2 HBr 5 2 Hz Brz K = 5.8 x 10-18 CH3CH(OH)COOH(aq) = CH3CH(OH)COO"(aq) + H+(aq) K= 1.4 x 10-4 5. Hydrogen chloride can be made from the reaction of chlorine and hydrogen: A (9) + H2(g) = 2 HQ(g) + heat (exothermic) Suppose that you have a closed reaction vessel containing an equilibrium mixture. Will the amount of Hal(g) increase, decrease or remain the same when The temperature is decreased. Additional Cla(9) is added to the mixture. A catalyst is added. Some hydrogen gas is removed from the mixture. Some helium is added to the mixture.
late for class please just help with these dont have time to make more posts

Answer 1

NH₃ (49) + H₂O(l) Nhut (aq) + oH (aq) K = 5.0x1012 to Here k)) I so right Products are favoured 2 HBr - 2H₂ + Brz K2 5.8*10-18 Here k41 7 Reactants are favoured enzent (OH) 200h (aq) = eu, CH(OH) 200 (aq) +it caq); K= luxioly - Here k value is true equilibriums and both productos reactants will be inequilibrium.
