WebThe integrated rate law for zero-order kinetics describes a linear plot of reactant concentration, [ A] t, versus time, t, with a slope equal to the negative of the rate constant, − k. Following the mathematical approach of previous examples, the slope of the linear data plot (for decomposition on W) is estimated from the graph. WebThus, the order can be negative only for the complex reaction, with respect to a substance, with undefined overall order.
