Answer:
rate=k×[C5H8]^n
k is the rate const.
when the rate is calculated using a few of the above data, (rate=change in concentration/time period) it can be observed that the rate is constant
therefore order of the reaction is 0
Answer:
1–ethoxybutane
Explanation:
In naming the above compound, the following must be observed:
1. The longest chain gives the root name of the compound.
2. The shorter chain is named as substituent together with the oxygen group as alkoxy.
3. Locate the position of the alkoxy group by giving it the lowest low count.
4. Combine the above to obtain the name of the compound.
Now we shall name the compound as follow:
1. The longest chain is carbon 4 i.e butane.
2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.
3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.
4. The name of the compound is:
1–ethoxybutane.
Answer: Hsub=Hfus+Hvap
Explanation:
The molar heat of vaporization measured in kilojoules per mole, or kJ/mol is the energy needed to make vapor one mole of a liquid. .
The molar heat of sublimation measured in kilojoules per mole, or kJ/mol is the energy needed to sublime one mole of a solid,
the molar heat of fusion measured in kilojoules per mole, or kJ/mol is the energy needed to melt one mole of a solid.
Hess law helps to explain the relationship in physical chemistry stating that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps.
In this context Hess’s law helps to see the several steps involved as the heat of sublimation energy is equal to the sum of vaporization energy and fusion energy.
1 atmosphere = 14.7 lb/in
So to convert lb/in to atmosphere, just divide by 14.7.
28.5 / 14.7 = 1.94 atmospheres.
