What do you understand by the 'order of a reaction'? Identify the reaction order from each of the following units of reaction rate constant:
(i) L-1 mol s-1 (ii) L mol-1 s-1
Order of reaction: The sum of powers of the concentration of the reactants in the rate law expression is called the order of that chemical reaction.
r = K Order = x y
(i) zero order (ii) second order
