Correct equation of Freundrich isotherm is

Correct equation of Freundrich isotherm is

Options

  1. Alog⁡(xm)=log⁡K+1nlog⁡C\log \left(\frac{x}{m}\right)=\log K⁺\frac{1}{n} \log C
  2. Blog⁡(mx)=log⁡K+1nlog⁡C\log \left(\frac{m}{x}\right)=\log K⁺\frac{1}{n} \log C
  3. Clog⁡(xm)=log⁡C+1Klog⁡C\log \left(\frac{x}{m}\right)=\log C+\frac{1}{K} \log C
  4. Dlog⁡(xm)=log⁡C+1nlog⁡K\log \left(\frac{x}{m}\right)=\log C+\frac{1}{n} \log K

Correct answer

A. log⁡(xm)=log⁡K+1nlog⁡C\log \left(\frac{x}{m}\right)=\log K⁺\frac{1}{n} \log C

Step-by-step solution

Freundlich gave an empirical relationship between the quantity of gas adsorbed by unit mass of solid adsorbent and concentration at a particular temperature. log⁡x/m=log⁡K+1n\logCx= mass of gas adsorbed, m= mass of adsorbent C= concentration, k,n= constants. \begin{aligned}& \log x / m=\log K⁺\frac{1}{n} \logC \\ & x=\text{ mass of gas adsorbed, } m=\text{ mass of adsorbent }\\ & C=\text{ concentration, } k, n=\text{ constants. } \end{aligned}
