The thermodynamic stabilities of the complexes of boron halides with trimethylamine increase in the order BF3 < BCl3 < B

The thermodynamic stabilities of the complexes of boron halides with trimethylamine increase in the order BF3 < BCl3 < BBr3.
Assuming that the formation reactions are exergonic at 25°C under standard conditions, construct reaction energy diagrams for the formation of the complexes of the three boron halides.
Be sure to make obvious in your diagrams the difference between the three.
A reaction energy diagram is a plot of Gibbs energy vs the progress of the reaction/reaction coordinate that specifies explicitly the positions of the reactant(s), transition state, and product(s) along the process.
