Hall-o equation for first-order reactions: 1/2 = 90 where his is the half-te in seconds(), and kis the rate constant in inverso seconds (!). 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] - [Aloe Now say we are particularly interested in the time would take for the concentration to become one. hall of its initial valuo. Then we could substitute AL for (A) and rearrange the equation to Part A To calculate the half-10, plug the value for k into the halle equation and solve What is the half of a first-order reaction with a rate constant of 1.50-10 Express your answer with the appropriate units This equation calculates the time required for the reactant concentration to drop to hit its initial value. In other words, it calculates the half- Value Units Submit Beste Part 3 What is the rate constant of a first-order reaction that takes 201 seconds for the reactant concentration to crop to half of its in bal value? Express your answer with the appropriate units Pearson
