Final answer:
The rate of decrease for NO in the given reaction cannot be determined based on the information provided.
Step-by-step explanation:
The rate of decrease for NO in the given reaction can be determined based on the stoichiometry of the reaction. The balanced equation for the reaction is 2NO + O₂ → 2NO₂. This means that for every 1 mole of O₂ consumed, 2 moles of NO are consumed. Therefore, the rate of decrease for NO is twice the rate of decrease for O₂.
Since there is no information provided about the rate of decrease for O₂ in the given reaction, we cannot determine the rate of decrease for NO based on the given information. Therefore, the correct answer cannot be determined from the options provided (A, B, C, D).
