360 minutes are required for 20 percent of a sample of cyclopropane to isomerize topropane.

Explanation:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

As the units of rate constant is , the reaction follows first order kinetics.

Expression for rate law for first order kinetics is given by:

where,

k = rate constant  =

t = time for decomposition = ?

a = let initial amount of the reactant = 100

x = amount decayed =

a - x = amount left after decay process  = 100-20= 80

Thus 360 minutes are requiredfor 20 percent of a sample of cyclopropane to isomerize topropane.

lol for the pointsss

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.
