Find the temperature from following graph so that highest amount of a gas is adsorbed

Step-by-step solution

Adsorption isotherms plot the extent of adsorption (x/m) against pressure (p) at constant temperatures. Since adsorption is exothermic, Le Chatelier's principle indicates that lower temperatures favor greater adsorption. The graph contains four isotherms labeled 195 K, 210 K, 244 K, and 273 K. The topmost curve, corresponding to 195 K, shows the highest (x/m) values across all pressures, confirming that maximum adsorption occurs at the lowest temperature. 195 K
