37. Option A, since it represents molar concentration
38. Option A, since it is a salt of HCl and KOH
39. Option A, both exothermic and endothermic reactions are reversible to each other
40. Option D, Kw = [H+][OH-] = 10-14
42. option C
43. Option C.
44. Option A, since no of atoms on reactant side should be equal to the no of atoms on product side.
