what does the value 0.92 cm3/g represent? and why is it multiplied by alpha? please answer. i need this for my calculations. why is the fractional coverage (theta)=alpha(0.92)
I don't know if you still need an answer or not. But, let me try to answer your question, The coverage (theta) is the adsorption capacity (wt%) over the maximum adsorption capacity (wt%_max) If you inverse the coverage function into variable K as a function of the coverage, you will get: K=1/P * (theta)/(1-theta) in this lecture 1/[(1-theta)*wt%_max] is simplified as alpha. so, you get : K = 1/P * (wt%) * alpha= (wt%)/P * alpha. That's why, for P=32 bar, you get K = 0.92/32 alpha = 0.02875 alpha. Hope it useful.

here, theta = 0.92/max_coverage. So alpha = 1/max_coverage
Lambda has to be less than 0..for adsorption is an exothermic process!
Correct answer or not. Please reply
