Question

What method is used to determine the form of the rate law - that is, what method is used to determine the rate law for a given reaction? Please explain your answer. Please differentiate between the zero, first, and second order rate laws? In addition, to explaining words, also differentiate between them graphically. What is a reaction mechanism? Explain the difference between uni molecular, bimolecular, and termolecular reaction? Given the Arrhenius Equation, K = A* [exp/RT)], explain what this equation means? Be specific.

Explanation / Answer

(1) Two methods to determine rate law

(i) Differential analysis method

(ii) Intergral method

(2)

Let the rate = k (C)n

If n= 0, then it is zero th law

if n=1, then it is first law

n=2 means second law.

(4) Writing the total equations that participate in the reaction

and then rate law corresponding to the slowest resction and mechanisms involving in total reactions

is called reaction mechansims

(5) if one molecule, 2 molecule, 3 molecule participate in rate equation then they are called uni, bi and ter molecular reactions respectively.
