A plausible graph of Δ r G 0 as a function of temperature for the reaction of 2 Ca(s)+O 2 ( g ) → 2 C a O ( s ) should be sketched. Concept introduction: In the graph of Δ r G 0 as a function of temperature, the dependent variable is Δ r G 0 . As a competition between Mg and Ca for O atoms, Mg has O initially in MgO, and Ca acquires them in forming CaO. This is represented by the following reactions. 2 Ca(s)+O 2 ( g ) → 2CaO(s) 2MgO(s) → 2 Mg(s) +O 2 ( g )
