Is it justified to compare the free energy change of two reactions and conclude one is more favourable than the other?

Suppose we consider the binding of a ligand L to a metal M, M+L=ML and M+2L=ML2 . We compute the Gibbs free energy change for two reaction using DFT. But can we compare this two free energies to...

Debashish Sengupta

Dear Dr. Martin Kohler,

I was very happy to receive your recent instructive reply and the details as requested. We are presently working on the beach placer deposits along the eastern coast of India enriched in zircons and monazites.. Some of our results are available in recent publications and some of them are under preparation. It would really interesting to get some of the ages in this regard to understand the provenance and the source rocks for the same.

Thanking you for the instructive Technical report/publication,

With Best Wishes

IIT Kharagpur West Bengal

Please send me your Email id so that I could send you our publication with Brad Van Gosen, as desired. I would be happy to send the relevant publication and some related publications

Best Wishes,

Dear Martin,

Thank you for sharing your instructive Report Book. The same would be very useful for our recent studies. Best Regards, Debashish
