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.

The half-life of a reaction,
t1/2, is the time it takes for the reactant concentration [A] to
decrease by half. For example, after one half-life the
concentration falls from the initial concentration [A]0 to [A]0/2,
after a second half-life to [A]0/4, after a third half-life to
[A]0/8, and so on. on. For a first-order reaction, the half-life is
constant. It depends only on the rate constant k and not on the
reactant concentration. It is expressed as t1/2=0.693k For a...

What is the difference between a first order and a second order reaction? a. For a first order reaction, plotting the natural logarithm of A versus time always gives a straight line with a slope equal to -k For a second order reaction a plot of 1 / A versus time, will produce a straight line with a slope equal to k b. For a first order reaction, plotting the natural logarithm of A versus time always gives a straight...

Which of the following statements is true concerning second order reactions? A. A plot of concentration vs. time will be a straight line. B. A plot of the reciprocal of concentration vs. time will be a straight line. C. A plot of ln of the concentration vs. time will be a straight line. D. None of the statements are true. E. The half-life of the reaction may be calculated using the equation: t1/2 = 1/k.

of nitrogen dioxide at 383 °C the concentration of NO2 was followed as a function of time. It was found that a graph of I/[NO2] versus time in seconds gave a straight line with a slope of 0.821 M1 s1 and a y-intercept of 3.46 MM1 Based on this plot, the reaction is order in NO2 and the rate constant for the reaction is In a study of the decomposition of dinitrogen pentoside in carbon tetrachloride solution at 30 "C...
