If the fugacity coefficient of the components of a binary mixture are = 0.784, and =0.638 and mole fraction of component 1 is 0.4, write down and expression for the fugacity coefficient inp, for the mixture.

Answer : The expression for the fugacity coefficient , for the mixture is, -0.3669.

Explanation : Given,

Fugacity coefficient of component 1 = 0.784

Fugacity coefficient of component 2 = 0.638

Mole fraction of component 1 = 0.4

First we have to calculate the mole fraction of component 2.

As we know that,

Now we have to calculate the expression for the fugacity coefficient .

Expression used :

where,

= fugacity coefficient

= fugacity coefficient of component 1

= fugacity coefficient of component 2

= mole fraction of of component 1

= mole fraction of of component 2

Now put all the give values in the above expression, we get:

Therefore, the expression for the fugacity coefficient , for the mixture is, -0.3669.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it takes on an electronical energy
