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

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

Answer

Brief Explanations:

The reaction requires 601.7 kJ of energy input. Temperature is related to the energy available to a system. Higher temperatures provide more energy which can drive endothermic reactions like this one. Concentration, pressure, and surface - area mainly affect reaction rates by changing collision frequencies, but they are not as crucial as temperature for a reaction that needs a large energy input to occur.

Answer:

temperature
