When a-iron is subjected to an atmosphere of hydrogen gas, the concentration of hydrogen in the iron, CH (in weight percent), is a function of hydrogen pressure, pH2 (in MPa), and absolute temperature (T) according to CHI=1.34102PH3exp(RT27.2N/mol) Furthermore, the values of D0 and Qd for this diffusion system are 2.6107m2/s and 13kJ/mol, respectively. Consider a thin iron Part 1 (a) What is the concentration of hydrogen at the low-pressure (or B) side in wt\%? CHij= (b) What is the concentration of hydrogen at the high-pressure (or A) side in wt\%? (a) What is the concentration of hydrogen at the B face in kilograms of H per cubic meter? C4H(t)= kg/m3 (b) What is the concentration of hydrogen at the A face in kilograms of H per cubic meter? What is the concentration gradient (C/x) in kg/m4 ?
