Formulating a reaction quotient

Formulate the reaction quotients for reactions A (the isomerism of glucose-6-phosphate) and B (the binding of oxygen to hemoglobin). 

Strategy Use Table 3.3 to express activities in terms of molar concentrations or pressures. Then use eqn 4.6 to write an expression for the reaction quotient Q. In reactions involving gases and solutes, the expression for Q will contain pressures and molar concentrations. 

Because we are not writing the standard concentration and pressure explicitly, this expression simplifies to 

CH3COOH + C2H5OH CH3COOC2H5 + H2O. (All four components are present in the reaction mixture as liquids the mixture is not an aqueous solution.)
