Answer 1

IVan, the first order reaction done exactly the way Damon worked that problem for you earlier. However, I don't believe that answer was right for a second order reaction. So plug that answer in for this problem and I posted what I think is a correction at the earlier post.

Answer 2

ok thank you, exactly what i needed to know .
