4. A Beer’s Law plot was prepared for the reaction A(aq) + B(aq)
AB(aq), plotting absorption over AB(aq) concentration. The linear equation for this plot was y = 78.3x.
A solution was prepared by mixing 10.0mL of 0.100M A with 5.00mL of 0.100M B and adding enough water to bring the total volume to 50.0 mL. The absorption of this solution was measured as 0.646.
Given this information, calculate the following:
a) The initial concentrations of each reactant.
b) The equilibrium concentration
of AB
c) The equilibrium concentrations of each reactant
d) The equilibrium constant with respect to concentration
