The half-life of a reaction, t1/2, is the time required for
one-half of a reactant to be consumed. It is the time during which
the amount of reactant or its concentration decreases to one-half
of its initial value.Determine the half-life for the reaction in
Part B using the integrated rate law, given that the initial
concentration is 1.95 mol⋅L−1 and the rate constant is 0.0019
mol⋅L−1⋅s−1
