Question

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

Answer 1

Temperature factor plays the most important role in the decomposition reaction of magnesium oxide.

What is spontaneous reaction?

Those reactions which are exothermic in nature or release heat during the reaction are spontaneous reactions.

Given decomposition reaction of magnesium oxide is:

MgO(s) + 601.7 kJ → Mg(s) + ½ O₂(g)

From the above reaction, it is clear that during the decomposition of magnesium oxide heat is absorbed. So, for the feasible decomposition of compound accurate temperature is wanted.

Hence, correct option is temperature.
