A marathon covers a distance of 26.2 miles. If 1 mile is equivalent to exactly 1760 yards, what is the distance of the race in y
1 answer:
Both mile and yard are units of distance thus they are inter convertible.
Distance covered in a marathon is 26.2 miles.
Since, 1 mile=1760 yards
Thus, distance can be converted into yards using the following conversion factor:
Thus, distance covered in marathon in yard will be:
Therefore, distance of the race is 46112 yards.

Explanation:
Since, the given reaction is as follows.
Hence, rate law of the reaction is as follows.
R =
As it is known that rate of a reaction depends on the initial concentration of products. So here, the rate of reaction will depend on the concentration of NO and . Since, power of the concentrations of each of these is equal to 1. Therefore, order of the reaction is equal to 1 + 1 = 2.
According to the rate law, reactants involved in the rate determining step are NO and . Hence, first step of the mechanism is the rate determining step.
Also, according to the rate of reaction doubling the concentration of NO will double the rate of reaction.
The number of reactants taking part in a single step of the reaction is known as molecularity of the reaction. Therefore, molecularity of the first step of the reaction is 2.
Both the given steps are not termolecular.
