A chemistry student wants to investigate the adsorption of a certain gas onto a solid surface. The student conducts an experiment and obtains the following data for different pressures of the gas:| Pressure (p) / atm | Quantity adsorbed (q) / g ||---|---|| 0.1 | 0.12 || 0.2 | 0.21 || 0.3 | 0.29 || 0.4 | 0.36 || 0.5 | 0.41 || 0.6 | 0.49 |Using the Langmuir adsorption isotherm, the student wants to determine the maximum amount of the gas that can be adsorbed onto the surface (q_max) and the rate constant for the adsorption process (k_ads). What are the values of q_max and k_ads for this gas-surface sys
