Write the expression for the equilibrium constant (Kc) for the reversible reactionN2(g) + O2(g) ⇌ 2NO(g) ... WebA weak base is any base that reacts with water (accepts H + ions) to a very small extent, usually less than 5 - 10%. An aqueous solution of a weak base in a state of equilibrium would consist mainly of the unionized form of the base, and only a small amount of hydroxide ions and of the cation (conjugate acid) of the weak base. church drapes and valances
