A thick wall made of natural rubber is exposed to pure oxygen gas on one side of its surface. Both the wall and oxygen gas are isothermal at 25°C, and the oxygen concentration at the wall surface is constant. Determine the time required for the oxygen concentration at x = 5 mm to reach 5 percent of its concentration at the wall surface. Oxygen gas 0 5 mm FIGURE P14-87 Rubber wall x
