Chemistry

Integrated Rate Laws: Working with Zero Order ReactionsExperiments have shown the following reaction to be zero order witha rate constant = 2.50 10-1 M/sec. A → B + 2 C If you started with[A] = 2.600 M, how many minutes until the concentration of A =2.300 M? .02 Correct: Your answer is correct. minutes How manyminutes until the concentration of C reaches equals0.899999999999999 M? 1.73 Incorrect: Your answer is incorrect.minutes

For zero order reactions [A] = [A]o - kt

Where

[A]o = initial concentration = 2.600M

[A] = concentration ate time t = 2.300 M

k = rate constant = 2.50x10-1 M/sec

t = time taken = ?

Plug the values we get t = ([A]o - [A]) / k

                                    = ( 2.600 - 2.300)M / (2.50x10-1 M/sec)

                                    = 1.2 s x ( 1 min / 60 s)

                                    = 0.02 min
