Calculate the Rate of Appearance of O₂ in a Chemical Experiment

What is the rate of appearance of O₂ in a particular experiment?

Given that INO₂ drops from 0.0100 to 0.00650 m in 100 s, what is the rate of appearance of O₂ for this period?

Answer:

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

The rate of appearance of O₂ can be determined by using the change in concentration of INO₂ over time. In the experiment at 300°C, the concentration of INO₂ drops from 0.0100 m to 0.00650 m in 100 s. This concentration change indicates the breakdown of INO₂ and the production of products, including O₂.

To calculate the rate of appearance of O₂, we can use the formula: Rate of appearance of O₂ = (final concentration - initial concentration) / time.

Plugging in the values, we get: 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 corresponds to option a) in the given choices.

This calculation helps us understand the relationship between the breakdown of INO₂ and the generation of O₂ in the chemical reaction taking place in the experiment at 300°C.
