A certain zero order reaction has a half live of 2.5 seconds when the initial concentration is 2.5 M. What concentration of the reactant remains after 4.5 seconds?
The reaction shown below obeys second order kinetics with k = 2.50 x 10-3 M-1s-1 at 25 oC. If the initial concentration of A is 2.00 M, how long will it take for concentration of A to decrease to 35.0 % of its original value?

A + A → products
For a certain second order reaction, k = 0.075 M‒1s‒1. If 0.0025 M of reactant remains after 15 minutes, how much of the reactant was present initially?
A certain reaction is known to be second order in [A]. What is the numerical value of k, the specific rate constant, if the concentration of [A] decreases from 1.50 M to 0.25 M after 225 seconds?
A certain reaction is known to be second order in A with k = 0.95 M‒1s‒1. What is the numerical value of the half-life (τ1⁄2) when the initial concentration of A is 0.45 M?
