The reaction of magnesium with oxygen is represented below.
2 mg (s) + o2(g) –> 2 mgo (s)
which best explains why increasing the amount of reactants increases the rate of the reaction?
a. the kinetic energy of the molecules increases because there is more mass in the system.
b.
the frequency of collisions increases because there are more molecules in a given
volume.
c.
the activation energy is lowered because oxygen gas is more reactive at high
concentrations.
d.
there is more space for molecular interactions because the system must expand to
accomodate more reactants.
