[求助] 扩散控制速率

请问各位大佬们,我最近投稿,审稿人提出一个关于过渡态和速率问题,见下文(包括问题涉及的相关内容)。这个我不太懂,能否请大佬们帮我看看,如何回答。非常感谢各位大佬们[抱拳][抱拳][玫瑰][玫瑰]

The discussion of the uranium chemistry has issues with it. There will be no transition state unless the reaction intermediate is quenched and with that much energy being released, that is unlikely. Effectively there is no barrier, and the reaction should be diffusion controlled. What is the diffusion controlled rate constant going to be?


Scheme 1.  hypothesized pathway of CO2 cleavage promoted by complexes RM (M = Cr, Mo, W and U).


Fig. 3. Gibbs free energy (ΔrG) profile for the pathway of the U complex-triggered reaction.
