Chem. 113C Homework Assignment # 5 Solutions Problem 1 Consider the schematic reaction a) If the reaction is one-half order with respect to [ A ], what is the integrated rate law expression for this reaction? b) What plot would you construct to determine the rate constant k for the reaction? c) What would be the half-life for this reaction? Will it depend on initial concentration of the reactant?
The half-life of 238 U is 4.5 x 10 9 years. How many disintegrations occur in 1 minute for a 10 - mg sample of this element?
For a type II second-order reaction, the reaction is 60% complete in 60 seconds when [ A ] 0 = 0.1 M and [ B ] 0 = 0.5 M. a) What is the rate constant for this reaction? b) Will the time for the reaction to reach 60% completion change if the initial reactant concentrations are decreased by a factor of two?
An experiment is performed on the generalized parallel reaction depicted in the lecture notes. Two things are determined: (1) The yield for B at a given temperature is found to be 0.3 and (2) the rate constants are described well by an Arrhenius expression with the activation to B and C formation being 27 and 34 kJ mol– 1 , respectively, and with identical preexponential factors. Demonstrate that these two statements are inconsistent with each other.
