Question

In a particular experiment at 300°C, INO₂ drops from 0.0100 to 0.00650 m in 100 s. The rate of appearance of O₂ for this period is ______ m/s.

a) 0.00035 m/s
b) 0.00045 m/s
c) 0.00055 m/s
d) 0.00065 m/s

Answer 1

The rate of appearance of O₂ for this period is 0.000035 m/s.

Step-by-step explanation:

The rate of appearance of O₂ can be determined by using the change in concentration of INO₂ over time.

Given that INO₂ drops from 0.0100 to 0.00650 m in 100 s, we can calculate the rate of change:

Rate of appearance of O₂ = (0.00650 m - 0.0100 m) / 100 s = -0.000035 m/s

Therefore, the rate of appearance of O₂ for this period is 0.000035 m/s (which is option a). The concentration of INO₂ drops in the experiment at 300°C from 0.0100 m to 0.00650 m in 100 seconds. This concentration change is a representation of the breakdown of INO₂ and the production of products, such as O₂. Since the breakdown of INO3 is directly linked to the generation of Oxygen gas (O₃), we can calculate the pace at which O₃ appears by examining the variation in INO3 concentration.
