Clock reaction rate law

WebIf the reaction is zero order with respect to A (rate is independent of [A]), then the rate law equation is rate ] dt k (22-4) Integrating the equation, then [A] = -kt + [A] o (22-5) Where [A] o is the initial concentration of reactant A and [A] is the concentration after time period t. WebAn instantaneous rate is the slope of a tangent to the graph at that point. An average rate is the slope of a line joining two points on a graph. If the two points are very close together, then the instantaneous rate is almost the same as the average rate.

The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. The iodine clock reaction exists in several variations, which each involve iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch. Two colourless solutions are mixed and at first there is no visible reaction. After a short time delay, the liquid suddenly turns to a shade of …
