Consider the first-order reaction described by the equation At a certain temperature, the rate constant for this reaction is 5.82 × 10 − 4 s − 1 5.82×10−4 s−1 . Calculate the half-life of cyclopropane at this temperature.

The half life of the reaction is 1190.7 seconds

Explanation:

The equation used to calculate rate constant from given half life for first order kinetics:

where,

k = rate constant of the reaction =

= half life of the reaction = ?

Putting values in above equation, we get:

Hence, the half life of the reaction is 1190.7 seconds

c.

explanation:

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.
