Question 48 of 201

For a first order reaction A$\to$ Product, the initial concentration of A is 0.1 M and after 40 minute it becomes 0.025 M. Calculate the rate of reaction at reactant concentration of 0.01M:

(a) 3.47x10^-4 M min^-1

(b) 3.47x10^-5 M min^-1

(c) 1.735 x 10^-6 M min^-1

(d) 1.735 x10^-4 M min^-1
