Consider the following reaction: 4 NH_{3} + 5 O_{2} → 4 NO + 6 H_{2}O The rate of consumption of NH_3 is -1.4×10^{-5} M/s. Calculate the relative reaction rate. Use “E” for scientific notation. Do not enter units as part of your answer.
could you possibly explain how to do this better? I'm not understanding how to calculate the data The rate of each reaction can be calculated by the expression R = d/t, where d = the distance in cm that the disk travels from the bottom of the container to the surface, and t = average time in seconds. The unit for the rate is cm/s. If the disk remains on the bottom of the container after 3 minutes, the distance traveled (d) will be zero, and the rate will be zero.
