Use the format: rate = -k[C]x to write a rate law for the reaction. [C] denotes the concentration of the food-colored solution. Based on the shape of the data series in your graphs, can you determine the reaction order, x? Have you seen data with this shape in this course before? Think. a) Substitute the appropriate digit for the value of x in the rate law and write the resulting equation in the space below (this is really simple
