| List $I$ | List $II$ |
| $A$ van't Hoff factor, $i$ | $I$ Cryoscopic constant |
| $B$ $k _{ f }$ | $II$ Isotonic solutions |
| $C$ Solutions with same osmotic pressure | $III$ $\frac{Normal\,molar\,mass}{Abnormal\,molar\,mass}$ |
| $D$ Azeotropes | $IV$ Solutions with same composition of vapour above it |
Choose the correct answer from the options given below :
$mA + nB + pC \to m' X + n 'Y + p 'Z$
obey the rate expression as $\frac{{dX}}{{dt}} = k{[A]^m}{[B]^n}$.
Reason : The rate of the reaction does not depend upon the concentration of $C$.
${C_6}{H_5}C{H_2}CH(OH)CH{(C{H_3})_2}\xrightarrow{{conc.\,{H_2}S{O_4}}}\,?$
