For the following reaction, the concentration of A and theamount of time required to decrease that concentration to one-halfof the initial concentration, t1/2, are directly proportional.Therefore, a decrease in concentration of A shows a proportionaldecrease in the half life, t1/2. What is the order of thisreaction? If the rate constant for this reaction is 0.0355 M·s–1 at400 °C, what is the half-life of this reaction, given an initialconcentration of 0.569 M.
