![Question 4
Kinetics
The formation of manganese oxide is an important consideration for many industrial processes, including
the purification of ground water. The rate of formation, however, depends on the presence of various
inert gases, M:
Mn2+ (s) + 0z(g) + M(g) # MnO2(s) + M(g)
A petrochemical plant wants to improve their filtration procedures by using nitrogen as an inert gas (M =
N2). Their research laboratory conducted the following kinetic experiments, involving different initial
concentrations of manganese and various mixtures of nitrogen and oxygen gas:

[N2].
