(1)
The observed half life for this reaction when the starting concentration is 0.401 Mis
sand when the starting concentration is O.201 M is
(2)
The average A(1/[NOBr]) / At from t-0s tot- 4.04 s is
The average A(1/[NOBr]) / At from t= 4.04 s tot- 12.1 s is
(3)
Based on these data, the rate constant for this
order reaction is
