Difference between rate of reaction and unique rate

Postby Ranger Saldivar 2D » Sun Feb 14, 2016 4:13 pm

In the book I was trying to solve problems for the rate of reaction for number 3 and i assume the rate of reaction just deals with the reactant NO2, but was confused on what the unique rate of reaction referred to. Can anyone clarify the differences and how to find it?

The unique rate of reaction is the rate of change in the concentration of a reactant or product divided by its stoichiometric coefficient in the balanced equation. I think question 3 is specifically asking about the unique rate of reaction of NO2, so you would divide the rate of reaction of NO2 by the coefficient, 2, to get the unique rate of reaction.
(6.5x10^-3 mol/Ls)/2=3.3x10^-3 mol/Ls

Unique rate is the overall rate of the reaction for that question.
