Product description
2.For this metal:
- Write a possible equation for the oxidation of a metal.
- For all substances participating in the reaction, write down the values
standard thermodynamic quantities ΔfH0298 and ΔfS0298, a, b, c.
- Determine the possibility of spontaneous oxidation of the metal under standard conditions using the chemical reaction isotherm equation.
- Determine the possibility of spontaneous oxidation of the metal at T = 450K and a partial oxygen pressure of 0.21 atm.
- Plot the dependence of ΔrG° on Т and mark on the graph the temperature range (shading) of spontaneous reaction.
- Determine the criterion for film continuity.
