Question

2A + 3B → 4C

At a certain point during the reaction shown above, the rate of appearance of C is measured to be 0.533 M/s. At this same point, what is the rate of the reaction?

Answer 1

2A + 3B ==> 4C

-1/2∆A / ∆t = -1/3∆B / ∆t = +1/4∆C / ∆t = rate of reaction

The rate of reaction may be different depending on if you look at disappearance of reactant or appearance of products, and the rates at which the different reactants and products change. The above describes the relationship among these different changes in concentrations and the rate.
