Given the reaction 2A + B -> 3C, the rate following the rate law would be . Using the unique rate instead of the rate law, you would calculate the rate by plugging in the values for any of these: . The unique rate can be calculated using the rate of formation of A or B, or by calculating the rate of decomposition of C (which would be the negative value of the other two rate of formations). The unique rate of formation takes into account the stoichiometric coefficients of the reaction while the rate law does NOT.

How would you determine the unique rate law if these two values are not the same? I'm super lost by how to differentiate between these two values.
