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-

a. hope i'm right

explanation:

it is the most commonly accepted one
