Experimental data for the one step reaction have been plotted in the following three different ways: [A] vs time (s), which gave a straight line relationship with a negative slope ln[A] vs time (s), which gave a curved plot 1/[A] vs time (s), which gave a curved plot What is the rate law of this reaction? (a) rate = k[A]2 (b) rate = k[A][B][C] (c) rate = k (d) rate = k[A] (e) rate = k[A]2[B] 2[C]

Although respiratory organs vary across different organisms, they all contain respiratory surfaces that have a large surface area and are extremely thin. explain why having an extremely thin respiratory surface with a large surface area is advantageous for the process of gas exchange
