When a graph is plotted between log `x//m` and log p, it is straight line with an angle `45^(@)` and intercept `0.3010` on `y-` axis . If initial pressure is `0.3` atm, what wil be the amount of gas adsorbed per gm of adsorbent `:`

Options

A. `0.4g`
B. `0.6g`
C. `0.8g`
D. `0.1g`

Answer

2

Explanation

`log. (x)/(M)=logk+(1)/(n)logP`
`(1)/(n)=tan 45^(@)`
`log k =0.3010`
`n=1`
`k=2`
`(x)/(M)=2xx(0.3)^(1)`
`x=0.6g`
