question 147

Multiple Choice

Determine the rate law and the value of k for the following reaction using the data provided. NO₂(g) + O₃(g) → NO₃(g) + O₂(g) [NO₂]_i (M) [O₃]_i (M) Initial Rate
0) 10 0.33 1.42
0) 10 0.66 2.84
0) 25 0.66 7.10

• A) Rate = 1360 M^-2.5s^-1[NO₂]^2.5[O₃]
• B) Rate = 227 M^-2.5s^-1[NO₂][O₃]^2.5
• C) Rate = 43 M^-1s^-1[NO₂][O₃]
• D) Rate = 430 M^-2s^-1[NO₂]²[O₃]
• E) Rate = 130 M^-2s^-1[NO₂][O₃]²

Definitions:

Cholecystokinin

Hormone liberated by the upper intestinal mucosa on contact with gastric contents; stimulates the contraction of the gallbladder and the secretion of pancreatic juice high in digestive enzymes.

Pancreatic Bicarbonate

A bicarbonate ion produced by the pancreas that neutralizes stomach acid as it enters the small intestine.

Secretin

Hormone formed by the epithelial cells of the duodenum; stimulates secretion of pancreatic juice high in bicarbonate ions.

Bile Production

The process of creating bile, a digestive fluid, by the liver and its storage in the gallbladder.
