A Proposed Mechanism for the Reduction of Nitrogen as NO $\rightarrow$

question 53

Multiple Choice

A proposed mechanism for the reduction of nitrogen as NO by hydrogen is:
Step 1: H₂(g) + 2 NO(g) $\rightarrow$ N₂O(g) F+H₂O(g) (slow)
Step 2: N₂O(g) +H₂(g) $\rightarrow$ N₂(g) +H₂O(g) (fast)
What is the rate law for step 1?

• A)k[H₂][NO]
• B)k[H₂][NO]²
• C)k[H₂]²[NO]
• D)k[H₂]²[NO]²
• E)More information is needed.

Definitions:

Discrete Random Variable

A variable that can take on a countable number of possible values, often representing counts or categories.

Expected Value

The long-run average or mean value of random variables, indicating the anticipated outcome of an experiment if it were repeated many times.

Discrete Random Variable

A variable that assumes a finite number of unique values, typically signifying the results of a stochastic process.

Continuous Random Variable

A type of random variable that can take an infinite number of possible values within a given range, often associated with measurements.
