Zero Order Reaction - Definition, Derivation, Graph, …

WebWhat is the approximate rate of reaction atfor the (a) zero-order, (b) first-order, (c) second-order reaction? WebSecond-Order Reactions We can derive the equation for calculating the half-life of a second order as follows: 1 [A]t = kt+ 1 [A]0 1 [ A] t = k t + 1 [ A] 0 or 1 [A] − 1 [A]0 =kt 1 [ A] − 1 [ A] 0 = k t Restrict t t = t1/2 t = t 1 / 2 then we can define [A]t = 1 2[A]0 [ A] t = 1 2 [ A] 0 and substitute into the integrated rate law and simplify: WebTherefore, the pseudo first-order reaction is a second-order reaction that behaves like a first-order reaction. Example: Hydrolysis of sucrose (C 12 H 22 O 11) gives glucose (C 6 H 12 O 6) and fructose (C 6 H 12 O 6). C 12 H 22 O 11 + H 2 O → C 6 H 12 O 6 + C 6 H 12 O 6.
