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.

answer: a chemical reaction

im not wrong

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
