PROBLEM SET 4 SOLUTION MASS BALANCES WITH CHEMICAL REACTIONS Question 12: Consider the reaction A Æ B taking place in a closed system. At t=0 the initial concentration of A is 3.5 mol/L and no B is present. After 1 hour, the concentration of A is down to 1.4 mol/L. 1) Assume that the reaction is 0 th order. Answer the following: a. Derive an expression for the concentration of A as a function of time. b. What is the value of k (including the units)? c. Calculate the half time. Show all derivations! 2) Now instead assume that the reaction is 1 st order, with the same concentrations of A initially and at 1 hour. Answer the same questions as in part (1). Answer on next page…
