The reaction `XrarrY` (Product ) follows first order kinetics. In 40 minutes, the concentration of X changes from 0.1M to 0.025 M , then rate of reaction when concentration of X is `0.01`M is :

For a first order reaction , A to Products, the concentrations of A changes from 0.1 M to 0.025 M in 40 minutes. The rate of reaction when the concentration of A is 0.01 M is:

A follows first order reaction. (A) rarr Product The concentration of A changes form 0.1 M to 0.025 M in 40 min . Find the rate of reaction of A when the concentration of A is 0.01 M .

(A) follows first order reaction, (A) changes from 0.1 M to 0.025 M in 40 min. Find the rate of reaction of A when concentration of A is 0.001 M.

The rate law expresses the relationship of the rate of a reaction to the rate constant and the concentration of the reactants raised to some powers for the general reaction. aA+bBtocC+dD Rate law takes the form r=k[A]^(x)[B]^(y) where x and y are number that must be determined experimentely k is the rate constant and [A] and [B] are concentration of A & B respectively. Gaseous reaction AtoB+C follows first order kinetics concentration of A changes from A changes from 1M to 0.25M in 138.6 min.Find the rate of reaction when conc. of A is 0.1 M.
