Exhibit 14-4 Consider the Reaction Below and Its Corresponding Equilibrium

question 133

Multiple Choice

Exhibit 14-4 Consider the reaction below and its corresponding equilibrium constant at 2000 C to answer the following question(s) :
N₂(g) + O₂(g) 2 NO (g) K c = 4.10 10 - 4 (at 2000 C)
Complete the table shown below for an experiment where 0.35 moles of N₂is mixed with 0.15 moles of O₂in a 1.00 liter reaction vessel and the reaction mixture is allowed to come to equilibrium. Concentration N₂O₂ 2 NO Initial 0.35 M 0.15 M Change At equilibrium
-Refer to Exhibit 14-4. After solving for x above, what is the concentration of NO at equilibrium?
You may make any simplifying assumptions that may make the solution of x easier.

• A) [NO]_eq = 5.38×10 ^{- 6} M
• B) [NO]_eq = 2.32×10 ^{- 3} M
• C) [NO]_eq = 4.64×10 ^{- 3} M
• D) [NO]_eq = 6.56×10 ^{- 3} M
• E) [NO]_eq = 9.28×10 ^{- 3} M

Definitions:

Region of Rejection

The part of the sample space where, if test statistics fall, the null hypothesis is rejected in favor of the alternative hypothesis in hypothesis testing.

Acceptance

The act of agreeing that something is satisfactory or adequate, often referring to the acceptance of hypotheses or theories based on evidence.

Statistic Probability

The likelihood of an event occurring based on the analysis of a set of predefined numerical data.

Null Hypothesis

In statistical testing, it's the presumption that there is no effect or difference among groups or variables being studied.
