Q-4 (7.10). The concentration of a reactant in a first-order chemical reaction that proceeds at a rate k can be described as follows: In(C) = ln(Co) - kt, where C is the concentration of the reactant at time t, Co is the initial concentration and t is the elapsed time since the reaction started. Consider an initial concentration of Co = 0.3 mol/L. The experiment was repeated n times to give a geometric mean of the concentration at time t...

The integrated rate law allows
chemists to predict the reactant concentration after a certain
amount of time, or the time it would take for a certain
concentration to be reached. The integrated rate law for a
first-order reaction is: [A]=[A]0e−kt Now say we are particularly
interested in the time it would take for the concentration to
become one-half of its initial value. Then we could substitute
[A]02 for [A] and rearrange the equation to: t1/2=0.693k This
equation calculates the time...
