The decomposition of nitrogen dioxide to nitrogen monoxide and oxygen gas is a second order process as suspected in the previous question. one would expect the second half-life of this reaction to be the first half-life of this reaction.

Explanation:

For the given reaction

Now, expression for half-life of a second order reaction is as follows.

                      ....... (1)

Second half life of this reaction will be . So, expression for this will be as follows.

          =  ...(2)

where is the final concentration that is, here and is the initial concentration.

Hence, putting these values into equation (2) formula as follows.

        =

                      =     ...... (3)

Now, dividing equation (3) by equation (1) as follows.

            =                  

                                    = 3

or,                       = 3    

Thus, we can conclude that one would expect the second half-life of this reaction to be three times the first half-life of this reaction.

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.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
