Question

INSTRUCTOR: SECTION Show all work for full credit 1. List the CAS number and hazards associated with each of the following chemicals a. Potassium iodate, KIO, b. Sodium bisulfite, NaHSO, 2. If the rate law for a reaction is rate - KIA[B]: a. What is the overall order of the reaction? If the concentration of A is doubled and the concentration of B is tripled, how will this affect the rate of the reaction? b. How will doubling the concentration of B while holding A constant affect the value of k (assuming that temperature remains constant)? c. © 2011 by bluedoor LLC (03-BC-081-5-2.07v) 57 THE IODINE CLOCK -REACTION KINETICS: PRE-LAB

Explanation / Answer

2)

a) As the power of conc of A is 2 and the power of conc of B is 1, the overall order of reaction is 2+1=3

b) If conc of A is doubled and the conc of B is tripled The rate will increase by (2^2)*(3^1)= 12 times

c) If the temperature is held constant and the concentration of species is changed, there will be ni change in rate constant as it solely depends on Temperature only.
