(B) The Freundlich adsorption isotherm equation is given by $\log (x/m) = \log k + (1/n) \log P$.Comparing this with the equation of a straight line $y = mx + c$,we have the slope $1/n = \tan 45^o = 1$ and the intercept $\log k = 0.3010$.Calculating $k$,we get $k = \text{antilog}(0.3010) = 2$.Substituting the values into the adsorption equation: $(x/m) = k \cdot P^{1/n} = 2 \times (0.3)^1 = 0.6$.

When a graph is plotted between $\log (x/m)$ and $\log P$,it is a straight line with an angle of $45^o$ and an intercept of $0.3010$ on the $y-$axis. If the initial pressure is $0.3 \ atm$,what will be the amount of gas adsorbed per $g$ of adsorbent $(x/m)$?

A
$0.4$
B
$0.6$
C
$0.8$
