In group theory, a branch of mathematics, the term order is used in two unrelated senses:
<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>
This article is about the first sense of order.
The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
It is a reaction that requires heat as a reactant.
First, assume the order of the given reaction is n, then the rate of reaction i.e. ![\frac{dx}{dt}=k\times[A]^{n}](https://tex.z-dn.net/?f=%5Cfrac%7Bdx%7D%7Bdt%7D%3Dk%5Ctimes%5BA%5D%5E%7Bn%7D)
where, dx is change in concentration of A in small time interval dt and k is rate constant.
According to units of rate constant, the reaction is of second order.
![\frac{1}{[A]_{t}}-\frac{1}{[A]_{o}} = kt](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BA%5D_%7Bt%7D%7D-%5Cfrac%7B1%7D%7B%5BA%5D_%7Bo%7D%7D%20%3D%20kt)
(second order formula)
Put the values,
t= 587.9 s
Hence, time taken is 587.9 s
Answer:169.87 g/mol
Explanation: (107.87 +14.007 + (3 x 15.999))= 169.874
Explanation:
You can test by putting sand in one cup and water in another. Then you put the thermometers in the cups. One you have done that you can use the heat lamp and put both cups under it for the same amount of time. After you do that and recorded your data you are done with the experiment.
Hope this helps :D
