[求助] 请问如何回答审稿人的这个问题啊,急等!!已有1人参与

it is stated that, -3d(NH3BH3)/dt = d[H2]/dt = k(catalyst. Figure 6b appears to show that that the rate (k) is not dependent on AB (ammonia borane). Figure 6b shows    ln(rate) = (0.0)ln[AB] - 0.16   or ln(rate) = -0.16   rate = 0.8521 a constant not dependent on AB. Given that rate or k is not dependent on AB then it would seem that d[H2]/dt would not equal -3d[AB]/dt; a zero order reaction with respect to AB.

审稿人的意思是说,你开始提到 -3d(NH3BH3)/dt = d/dt = k(catalyst. 但按你说法,如果Given that rate or k is not dependent on AB,就会出现 it would seem that d/dt would not equal -3d/dt。也就是说在审稿人看 ...

文献里也是这么报道的,斜率如果接近于零的话,可以认为是零级反应
