- At 127oC, HgI2 undergoes a polymorphic change from the red to the yellow form. The enthalpy of transition is 1250 J mol-1 , and the change in molar volume on transition is 5.4 cm3 mol-1 , the red form being the less dense. Calculate the rate of change of transition temperature with pressure at 127oC. Answer: [1.73 x 10-6 K Pa-1 ]arrow_forwardYou want to carburize a steel drill bit in the presence of methane. The drill bit initially has a uniform carbon concentration of 0.25 wt% and is to be treated at 950 oC (1750 oF). If the concentration of carbon at the surface is suddenly brought to and maintained at 1.20 wt%, how long will it take to achieve a carbon content of 0.80 wt% at a position 0.5mm below the surface? (The diffusion coefficient for carbon in iron at this temperature is 1.6 x 10-11 m2/s.)arrow_forwardAn iron-carbon alloy initially containing 0.240 wt% C is exposed to an oxygen-rich and virtually carbon-free atmosphere at 1100°C. Under these circumstances the carbon diffuses from the alloy and reacts at the surface with the oxygen in the atmosphere; that is, the carbon concentration at the surface position is maintained essentially at 0.0 wt% C. At what position will the carbon concentration be 0.180 wt% after a 7 h treatment? The value of D at 1100°C is 3.7 × 10-11 m2/s.arrow_forward
