A hypothetical diatomic molecule dissociates at 1000K with a first order rate constant of 1.00 s?¹. How long will it take for an initial sample of 1.00 mol of this molecule to dissociate so that there is .25 mol left? (A) 2 s (B) 1 s (C) .69 s (D) 1.39 s (E) 1000

Step 1
Since it is a first order reaction, the rate law can be written as: Rate = k[A] where [A] is the concentration of the diatomic molecule and k is the rate constant. Show more…

A second-order reaction starts with an initial concentration of 0.100 mol/L of the reactant. If the rate constant is 2.6 x 10^-2 L/mol·s, what is the time required to decrease the initial concentration to 0.050 mol/L? 2A → B rate = k[A]^2 a. 26.7 s b. 1100 s c. 570 s d. 384 s e. 1.92 s

The half-life of a reaction of compound $A$ to give compounds $D$ and $E$ is 8.50 min when the initial concentration of $A$ is $0.150 \mathrm{~mol} / \mathrm{~L}$. How long will it take for the concentration to drop to $0.0300 \mathrm{~mol} / \mathrm{~L}$ if the reaction is (a) first order with respect to $A$ or (b) second order with respect to $A ?$
