For the reaction x + y → z, the reaction rate is found to depend only upon the concentration of x. a plot of 1/x verses time gives a straight line. picture what is the rate law for this reaction?

a. rate = k [x]
b. rate = k [x]2
c. rate = k [x][y]
d. rate = k [x]2[y]

Option (b) is correct

Explanation:

For a second order of reaction of type:

Rate law is -  , where k is rate constant and [A] is concentration of A

Integrated rate law is-  , where is initial concentration of reactant A and [A] is concentration of A after "t" time (k and [A]_{0}[/tex] are constants)

The integrated rate law can be compared with y= mx+c equation for a straight line (x vs y) where is y and t is x.

As the rate of reaction depends only upon concentration of X therefore-

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
