1 Hydrogen gas at 85C is maintained at constant pressures of 11 atm and 4.2 atm on opposite sides of a 0.5-mm-thick nickel wall. Determine the molar diffusion rate per unit area through the nickel wall Nickel wall 10 points P Book Hydrogen SC Hydrogen PM References Given: Binary diffusion coefficient for hydrogen in the nickelot 85C is 120 x10-12 m/s The solubility of H2 in nickel at 85C is 0.00901 kmol/m bar x10*10 kmol/sm2 Round off to two decimal places.)
