The approximate partial pressure of oxygen at 1500 m is 0.18 atm.
<h3>Pressure of the air</h3>
From barometric pressure table;
1500 m = 85 kPa
1 kPa = 0.0099 atm
85 kPa = ?
= 0.84 atm
Oxygen percentage in air = 21%
<h3>Partial pressure of oxygen in air</h3>
P = 0.21 x P(total)
P = 0.21 x 0.84 atm
P = 0.18 atm
Thus, the approximate partial pressure of oxygen at 1500 m is 0.18 atm.

The rate of reaction may be determined using the concentration-time graph of either a reactant or product. The slope of the graph helps in determining the rate of reaction. If the rate of reaction increases, the magnitude of the slope of the graph will increase. This indicates that more reactant is being consumed per unit time, or, in the case of the product, more product is being produced per unit time.
