Select correct adsorption isobars for chemisorption and physisrption respectively (where x/m = extent of adsorption , T = temperature )
Which plot is the adsorption isobar for chemisorption where x is the amount of gas adsorbed on mass m (at constant pressure) at temperature T -
The correct statements pertaining to the adsorption of a gas on a solid surface are (i) Adsorption is always exothermic (ii) Physisorption may transform into chemisorption at high temperature (iii) Physisorption increases with increasing temperature but chemisorotion decrease with increasing temperature (iv) Chemisorption is more exothermic than physisoption, however, it is very slow due to higher energy of activation
Consider the adsorption isotherm given below and interpret the variation in the extent of adsorption (x/m) when a. Temperature increased at constant pressure. b. Pressure increases at constant temperature.
