The first order rate law has the form: -d[A]/dt = k[A] where, A refers to cyclopropane. We integrate this expression in order to arrive at an equation that expresses concentration as a function of time. After integration, the first order rate equation becomes:
ln [A] = -kt + ln [A]_o, where,
k is the rate constant
t is the time of the reaction
[A] is the concentration of the species at the given time
[A]_o is the initial concentration of the species
For this problem, we simply substitute the known values to the equation as in:
ln[A] = -(6.7 x 10⁻⁴ s⁻¹)(644 s) + ln (1.33 M)
We then determine that the final concentration of cyclopropane after 644 s is 0.86 M.
Molar mass of salt = 58.44 grams/mole
In the north Atlantic the movement of tectonic plates(if that is what you meant by plates) is around.4 inches per year which is almost 1 cm but in the pacific area the movement is almost 2 inches which is more that four cm every year although some people say that they (in general not specific to any place in particular) travel in the range of 5-10 centimeters every year.
Answer:
science literacy among people has contributed a lot to the growth and progress of our economy considering the state of our society these days. People who have knowledge in science literacy indeed has contributed a lot of things for the betterment of society. Even though we have an unstable society, these “knowledge” has made its way to the top. In fact, it has contributed a lot of change for the economy. People who have the heart in science literacy must also have the heart in helping others so that their knowledge would also benefit those who are in dire need of support and help. Everything and anything these days are answerable by science and I think it would be great and easy to practice more of it.
