WebThe reaction rate is a measure of how fast a chemical reaction proceeds and is expressed as a concentration change (of reactants or products) over time. Given that the food color disappears throughout the reaction, the reaction rate can be defined by the concentration change of the colored reactant over time, as stated in following rate law: 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). raymond enders apartments portland tn
