Homework Answers
Let the rate law of the reaction is given by
![Rate = k[X]^a[Y]^b](http://img.homeworklib.com/questions/0327b010-b59e-11eb-b667-c1be82adb1f9.png?x-oss-process=image/resize,w_560)
using the data given in the table we get
![1.4 * 10^{-3} = k[0.4]^a[0.2]^b --- (i)](http://img.homeworklib.com/questions/039e9100-b59e-11eb-b52b-03c05319ce3e.png?x-oss-process=image/resize,w_560)
![2.8 * 10^{-3} = k[0.4]^a[0.4]^b --- (ii)](http://img.homeworklib.com/questions/04114130-b59e-11eb-99fe-09d56cc608c5.png?x-oss-process=image/resize,w_560)
dividing the first equation by second equation we get
Hence the rate law of the equation will be given
Rate = k[Y]
rate constant = 7 * 10^(-3) s^(-1)
ln(Ao/At) = kt
ln(0.6/0.4) = kt
t = ln(1.5)1000/7 = 57.923 seconds
