A reaction is found to be second-order with a rate constant of 3.45 × 10–5 M–1 s–1. The reaction initially began with 4.354 M reactant. How much reactant remains (in M to two decimal places) after 1 hour?
For the given generic reaction, the concentration of A and the amount of time that is required to decrease the concentration to one-half of the initial concentration, t1/2, are directly proportional. Therefore, a decrease in the concentration of A shows a proportional decrease in the half-life, t1/2.
For the reaction A → B, a plot of ln[A] vs. time yields a straight line with the equation y= -0.423 + 0.092x. What is the reaction order with respect to A? What is the half-life of the reaction in (s) ? What was the initial concentration of A (M) ?
