Question

The enthalpy change for the adsorption process and micelle formation respectively are

Select the correct option:

$\Delta \mathrm{H}_{\text {ads }}<0$ and $\Delta \mathrm{H}_{\text {moic }}>0$

$\Delta \mathrm{H}_{\text {ads }}<0$ and $\Delta \mathrm{H}_{\text {mic }}<0$

$\Delta \mathrm{H}_{\text {ads }}>0$ and $\Delta \mathrm{H}_{\text {mica }}<0$

$\Delta \mathrm{H}_{\text {ads }}>0$ and $\Delta \mathrm{H}_{\text {mic }}>0$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Adsorption is exothermic process due to decrease in surface energy Micelle formation is endothermic
