Benzene has a heat of vaporization of 30.72;{{rm{kJ}}}/{{rm{mol}}} and a normal boiling point of 80.1 ^circ {rm{C}}. At what temperature does benzene boil when the external pressure is 420 torr?
Adenosine monophosphate (AMP) is a regulatory molecule in metabolic processes such as glycolysis and gluconeogenesis. For example, it stimulates the glycolytic enzyme phosphofructokinase, and therefore ATP production, and it inhibits the gluconeog..
