Plots of logvs.log C showing a straight line parallel to X-axis reveals that:a)n = 0b)c)C = 0d)log C = constantCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Answer

Yes, the answer is correct, its option 'b'. This is a plot of log(x/m) vs log(c) from the *Freundlich Isotherm* which is expressed by the equation ―>
log(x/m) = log(k) + (1/n) log(c) ............(i)
Now according to the question, the plot is a straight line parallel to the X-axis and its general equation is,
y [here, log(x/m)] = constant
So, the RHS of the equation (i) to be constant, i.e., log(k), the value of '(1/n) log(c)' has to be 0. And that can be achieved only by the condition 1/n = 0.

Answer

Slope is  1/n , But parallal to x axis so that slope is zero ...ie, 1/n is zero
