The Decomposition of N₂O₅ in Solution in Carbon Tetrachloride Proceeds

question 115

Multiple Choice

The decomposition of N₂O₅ in solution in carbon tetrachloride proceeds via the reaction 2N₂O₅(soln) → 4NO₂(soln) + O₂(soln)
The reaction is first order and has a rate constant of 4.82 × 10^-3 s^-1 at 64 °C. If the reaction is initiated with 0.058 mol in a 1.00 L vessel, how many moles remain after 151 s?

• A)0.055 mol L^-1
• B)0.060 mol L^-1
• C)0.028 mol L^-1
• D)12 mol L^-1
• E)2.0 × 10³ mol L^-1

Noncoding Region

Sections of DNA that do not code for proteins but may have regulatory roles in gene expression, chromatin structure, and genome organization.

IGF2 Gene

A gene that encodes the insulin-like growth factor 2, playing a crucial role in growth and development, especially fetal growth.

Lactose Repressor

The lactose repressor is a protein that binds to the promoter region of the lactose operon in bacteria, regulating the metabolism of lactose by inhibiting the transcription of lactose-utilizing genes.

Transcription

The process in which the DNA sequence in a gene is copied into mRNA, serving as the first step in gene expression.
