WebReaction rates can be measured by the disappearance of starting material or the appearance of the product over time. Instantaneous reaction rates can be determined from the slope of the tangent at that point in the plot of concentration vs. time. The initial reaction rate is the instantaneous rate at the start of the reaction (at t = 0).
