In the reaction A to products, A is found to be 0.489 M at t=72.0 s and 0.468 M at t=82.2 s
What is the average rate of the reaction during this time interval?
Do I take the Ln (0.468/0.489) = -0.04395 / 10.2 = 4.3 * 10^3. yet the comp says its wrong. i have to put it to two sig figs. someone help?
