A rate constant obeys the Arrhenius equation, the factor A being 2.2 10^13 s-1 and the
1 answer:
4.743 x s-1 is the value of the rate constant.
The Arrhenius equation describes the relationship between the rate of reaction and temperature for many physical and chemical reactions.
As per Arrhenius equation,
k = Ae-Ea÷RT
T = 227 = 500.15 K
R = 0.008314 kJ/K mol
Ea = 150 kJ/mol
Ea÷RT
= 150÷(0.008314 x 500.15)
= 36.073
k = Ae-36.073 = (2.2 x s-1) (2.156 x
)
k = 4.743 x s-1
So, the correct answer is option d) i.e. 4.7 x s-1
As per Arrhenius equation,
k = Ae-Ea/RT
T = 227 = 500.15 K
R = 0.008314 kJ/K mol
Ea = 150 kJ/mol
Ea÷RT = 150÷(0.008314 x 500.15) = 36.073
k = Ae-36.073 = (2.2 x s-1)(2.156 x
)
k = 4.743 x s-1
Hence, 4.743 x s-1 is the value of the rate constant.

Explanation:
Conjugated diene is the one that contains alternate double bonds in its structure. That means both the double bonds are separated by a single bond.
Cumulated diene is the one that contains two double bonds on a single atom. This means it has two double bonds continuously.
Isolated double-bonded compound has a single bond isolated by two to three single bonds.
Compound A: Two alkenes are joined by a sigma bond.
For example:
It is a conjugated diene.
Compound B: Two alkenes are joined by a C H 2 group.
It is a cumulative diene.
Compound C: Two alkenes are joined by C H 2 C H 2.
Then it is an isolated alkene.
Compound D: A cyclohexene has a double bond between carbons 1 and 2. Carbon 3 is an sp 2 carbon that is bonded to another s p 2 carbon with an alkyl substituent.
Hence, compound D is a conjugated diene.
