A certain reaction obeys second-order kinetics with respect to its only reactant (call it R) and has a rate constant of 0.0520 L mole-1 s-1. If the initial concentration of reactant R is 0.265 moles/liter, what is the concentration of R after 3.50 minutes? _______________
Question 6 (5 points) A reaction that is second order in a single reactant has an initial concentration of 0.910 M and a rate constant of 0.441 M-18-1. What is the concentration of this reactant at 94.0 s? 0.00907 M 0.157 M 0.420 M 0.365 M 0.0235 M
Question 5 (5 points) A reaction that is second order in a single reactant has an initial concentration of 0.910 M and a rate constant of 0.441 M-15-1. What is the concentration of this reactant at 94.0 s? 0.0235 M 0.00907 M 0.157 M 0.420 M 0.365 M
If a reaction is second order in reactant A, what happens to the rate of the reaction if the concentration of A is halved (divided by 2)?
A reaction that is second order in one reactant has a rate coefficient of 0.05 dmmols1. If the initial concentration of the reactant in 0.1 mol dm, how long will it take (in seconds) for the concentration to become 0.05 mol dm 3? Express your answer in seconds, correct to two decimal places. Please do not include the correct units (seconds) in your answer.

B) What is the concentration of A after 32 s have passed? B) After what time will the concentration of A be [A]o 16?
The reactant concentration In a second order reaction was 0.340 M After 280 seconds and 3.80×10^-2 M after 850 s. what is the rate constant for this reaction? Part D The reactant concentration in a second-order reaction was 0.340 M after 280 s and 3.80x10-2 M after 850 s. What is the rate constant for this reaction? Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash....
Most of the time, the rate of a reaction depends on the concentration of the reactant. In the case of second-order reactions, the rate is proportional to the square of the concentration of the reactant. Select the image to explore the simulation, which will help you to understand how second-order reactions are identified by the nature of their plots. You can also observe the rate law for different reactions. In the simulation, you can select one of the three different...
