Water’s power as an ionizing solvent results from two features of the water molecule: the distribution of its bonding electrons and its overall shape. Recall from Section 2.7 that the electrons in a covalent ...

... The Henry’s law constant for N2(g) at 298 K is 6.8 × 10–4 mol L–1 atm–1. A diver descends to a depth where the pressure is 5 atm. If the diver’s body contains about 5 L of blood, calculate the maximum amount of nitrogen gas dissolved in the diver’s blood at 1 atm and at 5 atm. (Assume solubility of ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
