The enthalpy of the reaction

Reference no: EM13535791

C (dissolved in steel) + O (dissolved in steel) = CO (g)

The enthalpy of the reaction is 22.4 kj/mol CO and the entropy of the reaction is 39.6 kj/K mol CO for a standard state (consisting of 1 weight percent of Oxygen and 1 weight percent of Carbon in steel).
If a steel contains 0.3 weight percent carbon, calculate the amount of Oxygen in the steel if the steel is in equilibrium with a partial pressure of 1 atm CO at 1600 degrees Celsius. Assume that the activity coefficients of Carbon and Oxygen in Steel are both unity (solute concentrations expressed as weight percent).

Sketch a plot of ln(carbon content) versus ln(oxygen content) for higher and lower partial pressures of CO and write on your plot the slope of the lines produced.
