Statement-II: Adsorption enthalpy for physisorption is less compared to adsorption enthalpy for chemisorption.
The correct answer is:
Identify the autocatalytic reaction from the following:
Two statements are given below
Statement I: Adsorption of a gas on the surface of charcoal is primarily an exothermic reaction
Statement II: A closed vessel contains O$_2$, H$_2$, Cl$_2$, NH$_3$ gases. Its pressure is P (atm). About 1 g of charcoal is added to this vessel and after some time its pressure was found to be less than P (atm)
The correct answer is
The validity of Freundlich isotherm can be verified by plotting:
Which of the following has maximum coagulating power in the coagulation of positively charged sol?
The critical temperature of A, B, C, D gases are 190 K, 630 K, 261 K, 400 K respectively. The quantity of gas adsorbed per gram of charcoal at same pressure is least for the gas
