In an experiment measuring the efficacy of bioremediation for a toxic organic pollutant, the following data was obtained. Use the data (below) to answer the following questions.

Time (days) Concentration (mg/L)
0 66.99
0.5 43.59
1 24.67
2 9.333
3 3.523
5 0.447
12 6.667 x 10^-4

What is reaction rate constant for the process?

a. 0.96 hr-1
b. 0.48 hr-1
c. 0.10 hr-1
d. 0.04 hr-1
e. 1 hr-1

Given the rate obtained in above question, how much time is required to achieve log 3 transformation (removal) of the organic pollutant?

a. 7.17 days
b. 0.768 days
c. 27.4 days
d. 172.2 days
e. 1.14 days

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
