For the following reaction, the concentration of A and the amount of time required to decrease that concentration to one-half of the initial concentration, t1/2, are directly proportional. Therefore, a decrease in concentration of A shows a proportional decrease in the half life, t1/2. What is the order of this reaction? If the rate constant for this reaction is 0.0355 M·s–1 at 400 °C, what is the half-life of this reaction, given an initial concentration of 0.569 M.

Reaction time studies are studies in which participants receive a stimulus and the amount of time it takes for them to react is measured. In one simple type of reaction time study, each participant holds a clicker button and stares at a screen. When the participant sees a part of the screen light up, he or she clicks the button as quickly as possible. The researcher then records how much time elapsed between when the screen lit up and when...
