Answer» SOLUTION :Explanation : CONSIDER the following reaction. `AA + bB rarr "products "` It the rate of the reactiondepends on the concentrations of the reactantsA and B, thenby rate law, `R prop [A]^(a) [B]^(b)` `:. R = k[A]^(a)[B]^(b)` Where [A] = concentrationof A and [B] = concentration of B The proportionality constant k is calledthe VELOCITY constant, rate constant or specific rate of the reaction. a and b are the exponents or the powersof the concentrations of the reactants A and B respectivelywhen observedexperimentally. Example : `H_(2^((g))) + I_(2(g))` `R = k[H_(2)][I_(2)]` |
