If you take organic chemistry laboratory (chm2211l) you will learn the term reflux. a reaction is considered to be at reflux when it is set at the boiling point of your solvent. a. in order to bring 74.81 ml of chloroform (density = 1.4832 g/cm3 , c = 0.96 j/g*k ) to reflux from room temperature (25 oc) it requires 1.46 kj of energy. what will be the temperature (in of) of the chloroform?

Answer : The temperature of the chloroform will be,

Explanation :

First we have to calculate the mass of chloroform.

conversion used :

Now we have to calculate the temperature of the chloroform.

Formula used :

where,

q = amount of heat or energy = 1.46 kJ = 1460 J   (1 kJ = 1000 J)

= specific heat capacity =

m = mass of substance = 110.958 g

= final temperature = ?

= initial temperature =

Now put all the given values in the above formula, we get:

Now we have to convert the temperature from Kelvin to Fahrenheit.

The conversion used for the temperature from Kelvin to Fahrenheit is:

As we know that, or,

 ...........(1)

Now put the value of temperature of Kelvin in (1), we get:

Therefore, the temperature of the chloroform will be,

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
