The chemical reaction that causes magnesium to corrode in air is given by 2Mg+O2â2MgO in which at 298 K ÎHârxn = â1204 kJ ÎSârxn = â217.1 J/K
Part A What is the standard Gibbs free energy for this reaction? Assume the commonly used standard reference temperature of 298 K. Express your answer as an integer and include the appropriate units. ÎGârxn = 6K
Part B What is the Gibbs free energy for this reaction at 5958 K ? Assume that ÎH and ÎS do not change with temperature. Express your answer to two decimal places and include the appropriate units. ÎGrxn =
Part C At what temperature Teq do the forward and reverse corrosion reactions occur in equilibrium? Express your answer as an integer and include the appropriate units. Teq =
