Recall that for a reaction aA  bB, the rate of a reaction is given by:

$\overline{){\mathbf{Rate}}{\mathbf{=}}{\mathbf{-}}\frac{\mathbf{1}}{\mathbf{a}}\frac{\mathbf{\Delta }\mathbf{\left[}\mathbf{A}\mathbf{\right]}}{\mathbf{\Delta t}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{b}}\frac{\mathbf{\Delta }\mathbf{\left[}\mathbf{B}\mathbf{\right]}}{\mathbf{\Delta t}}}$

###### Problem Details

What is the average rate of formation of I2? Express your answer to three decimal places and include the appropriate units.

Now consider the following reaction and data:

H2 + 2 IF → 2 HF + I2

 Time       (s ) I2 concentration            (M ) 5 1.12 15 1.56
