Unformatted text preview: at C and at C. What are the activation energy and preexponential factor ( ) for this reaction? [10 marks] 5. The third-order equation is 1. Define half-life. [2 marks] 2. Derive an expression for the half-life of a third-order reaction in terms of the initial concentration of the reactant and the rate constant. [8 marks] 3. For [A] in mol/L and time in s, what are the units of a third-order rate constant? Hint: This is just a matter of unit analysis. [2 marks] 4. You are told that a certain reaction obeys third-order kinetics. Explain how you would use this equation along with data giving [A] as a function of time to obtain the rate constant.
