Phenyl Propyl Ketone is prepared from
Butanoic acid as follow,
First Butanoic acid is treated with
thionyl chloride so to change the -OH group into good leaving group (i.e. -Cl) and
Butyryl chloride is generated.
Secondly, Chlorination of
Benzene is done to synthesize
chlorobenzene which on treatment with Mg metal in ether is converted into
Phenyl Magnesium Chloride, which acts as a nucleophile and attacks the carbonyl carbon of Butyryl Chloride and upon hydrolysis gives Phenyl Propyl Ketone as shown below,
Explanation:
Change in the concentration of reactant that is consumed in per unit time is known as rate of reaction.
The given chemical reaction will be written as follows.
Hence, rate law for the given reaction will be as follows.
Rate = k
where, k = rate constant
= initial pressure of the pollutant X
It is given that, = initial partial pressure of X = 0.473 atm
= final partial pressure of X = 0.376 atm
Time = 5.6 hours
Hence, formula for rate constant of first order reaction is as follows.
k =
=
= 0.041 per hour
Therefore, rate of decomposition will be calculated as follows.
Rate = = k
=
=
Thus, we can conclude that initial rate of decomposition of X is .
If iodine has a 13.3 hour half life, 3.12 mg of the original sample will still be present after 39.9 hours.
<h3>what is The meaning of half-life?</h3>
The reaction rate must decrease to half its initial value before the process has reached its half life. The split of that first order chemical reaction is a quantity related to the rate constant of the reaction.
Briefing:
Given, the iodine half-life is 13.3 hours. As a result, half-life t1/2 Equals ln 2/ K
k = 0.693 .... t1/2
≈ 0.693 /13.3 hours
= 5.21 *10-2
The rate law sets the flow timetime is set by the rate law, which varies for each emotion. When only one reactant's quantity influences the speed of chemical reaction, this is referred to as a first-order contact. Because of this, it is occasionally referred to as unimolecular process. The rate is as follows for this type of reaction: k= 1/t ln [A]0 / [A] is the rate constant for the first order reaction. 5.21 * 10-2 hours are in 39.9 hours.
By including all the numbers in the initial order reaction's rate constant equation, we obtain [A].
t = 3.12mg
