The correct values of 'K' and 'n' are, respectively, — Surface Chemistry Chemistry Question

💡 Solution & Explanation

According to the Freundlich equation, log(x/m) = log K + (1/n)log P. The slope of the line is 1/n = tanθ = 0.25, which gives n = 4. The line passes through the x-axis at -4.0, so when log P = -4.0, log(x/m) = 0. Substituting these values: 0 = log K + 0.25(-4.0) => log K = 1, giving K = 10. Therefore, correct answer is B.
