Incorrect. We learned in the previous problems that this reaction is second order and k = 0.25 M²¹ s²¹.
During the first half-life, [A] decreases by 50% (0.2 M to 0.1M). Now we need to determine how long it will take for [A] decrease by
another 50% (0.1 M to 0.05 M). This means the original concentration for the second half-life of experiment #2 is 0.1 M.
