ACTIVITY OF SOLUTE B
Definition
An <ACTIVITY OF SOLUTE B> is an <IndirectProperty> where, for a solute B in a solution, a_B is proportional to the absolute activity lambda_B, the proportionality factor, which is a function of <TEMPERATURE> and <PRESSURE> only, being determined by the condition that, at constant <TEMPERATURE> and <PRESSURE> a_B divided by the molality <RATIO> m_B/m^Theta, tends to 1 at infinite dilution; b_B is the molality of solute B, and b^Theta is standard molality, usually 1 mol/kg
