Which property increases with increasing atomic number for both the alkali metals and the halogens?
1 answer:
To answer this question,you must be knowledgeable on periodic trends. When the atomic number increases, that means that the trend of the property must increase both across the period and down a group. The alkali metals are the elements in the leftmost column, while the halogens are the second-to-the-last column. From the periodic trends shown in the picture,<em> the property must be atomic radius.</em>

<u>Answer:</u> The fugacity coefficient of a gaseous species is 1.25
<u>Explanation:</u>
Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as
Mathematically,
Partial pressure of the gas is expressed as:
Putting this expression is above equation, we get:
where,
= fugacity coefficient of the gas
= fugacity of the gas = 25 psia
= mole fraction of the gas = 0.4
P = total pressure = 50 psia
Putting values in above equation, we get:
Hence, the fugacity coefficient of a gaseous species is 1.25
