1) Option b: gas pressure.
This is sustainted by the kinetic molecular theory of the gases.
2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.
PV = nRT
If V and n are constant, P is proportional to T, then if T increase P will increase too.

Answer:
The reaction must be spontaneous, the disorder of the system increases.
Explanation:
By the Second Law of Thermodynamics, a positive change in entropy is due to a net input heat, and entropy is a measure of the grade of disorder within the system. The net input heat means that resultant goes to the system from the surroundings.
By the First Law of Thermodynamics, a net input heat is due to a positive change in enthalpy.
The reaction is endothermic and spontaneous (since change in entropy is positive).
4Fe + 3O2 -> 2 (Fe2O3)
Both sides have 4Fe and 6O.
In the context of chemistry, yes. Energy input is always equal to the energy output.
