Dr. Burrow
I have another question that i couldn't solve

The following reaction was monitored as a function of time:
AB --> A + B
A plot of 1/[AB] versus time yields a straight line with slope 5.4 x 10^-2 M.s

If the initial [AB] is 0.290M, and the rxn mixture initially contains no products, what are the concentration of A and B after 80s.

(this problem is about integrated rate law and half-life)

zậy chéc kỉu này khỏi fải lên lớp chi nữa cho mệt, ở nhà google search thôi
