Embibe Experts Solutions for Chapter: Chemical Kinetics, Exercise 5: EXERCISE-IV (Assertion & Reason)

Assertion: Two different reactions can never have same rate of reaction.

Reason: Rate of reaction always depends only on frequency of collision and Arrhenius factor.

Which of the following is used to absorb water?

The heat evolved in physisorption lies in the range $(\mathrm{kJ}/\mathrm{mol})$ of:

A plot of $\log \frac{\mathrm{x}}{\mathrm{m}}$  versus $\log \mathrm{p}$ for the adsorption of a gas on a solid gives a straight line with a slope equal to 

$1 \mathrm{g}$ of charcoal having surface area $3.02\times {10}^2 {\mathrm{m}}^2$ is mixed in $100 \mathrm{ml}$ of $0.5 \mathrm{M}$ acetic acid solution; after few times concentrations of solution becomes, $0.49 \mathrm{M}$. What will be surface area occupied by one molecule of acetic acid?
