Since we are is the mainly concerned with relative rather than absolute rate we will for convenience take all relative rates as being equal to 1000%. Fill in the following table, first calculating the relative reaction rate for each mixture.

Since we are dealing with relative rates, we can modify Equation 2 to read as follows: relative rate= ( BrO, YCHY (continued on the following page)

Answer 1

reactant concentration in reacting mixture reaction mixture relative rate of reaction(100/t):
