Magnesium oxide does not readily decompose into magnesium and oxygen. the reaction is shown below. mgo(s) + 601.7 kj mc017-1.jpg mg(s) + ½o2(g) which factor plays the most important role in allowing this reaction to occur? temperature concentration pressure surface area mark this and return

Answer is: temperature.

Balanced chemical reaction: MgO(s) + heat → Mg(s) + 1/2O₂(g).

This is endothermic reaction (ΔH > 0, chemical reaction that absorbs more energy than it releases). In endothermic reactions heat is reactant.

Because magnesium oxide (MgO) is in solid state, concentration, pressure and surfuce does not play the most important role in allowing this reaction to occur.
