The mass of hydrogen gas adsorbed on the surface of 10 g platinum at 16 atm is — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Using the isotherm x/m = K·P^(1/n) with derived values K = 10 and n = 4. At P = 16 atm, x/m = 10 × (16)^(1/4) = 10 × 2 = 20. Given m = 10 g, the mass of gas adsorbed x = 20 × 10 = 200 g. Therefore, correct answer is A.
