Consider the reaction: 3a + b + 2 c æ d + e where rate = k[a]2 [c]2 . a reaction was performed where [b]o = [c]o = 0.500 m and [a]o = 3.20 x 10-5 m. a plot of 1/[a] vs time (min) gave a plot with a straight line relationship and after 3.00 min, [a] = 2.7 x 10-6 m. what was the initial rate of the reaction described above?
