Question 1 :

The standard enthalpies of formation, at 25.00 ^oC, of methanol (CH₄O(l)), water (H₂O(l)), and carbon dioxide (CO₂(g)) are, respectively, -238.7 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. Calculate the change in the entropy of the surroundings (in J/K) upon the combustion of 15.1 g of methanol under a constant pressure of 1.000 atm and a temperature of 25.00 ^oC. N.B. combustion is the reaction of this substance with molecular oxygen to produce water and carbon dioxide.

Question 2 :
At 25^oC, the equilibrium constant for the reaction 2 A(aq) —-> B(aq) + C(aq) is 2.20 . If the concentration of B(aq) is 0.333 M and the concentration of C(aq) is 0.537 M, what would be the minimal concentration of A(aq) (in mol/L) required to make the reaction spontaneous?

Question 3 :
For the reaction A(aq) + B(aq) <—> C(aq) + D(aq), the equilibrium constant is 23.7 at 25^oC and 35.0 at 50^oC. What is the value of the standard Gibbs free energy change (in kJ) of this reaction at 75^oC?

Question 4 :
We have a solution that has a concentration of 0.362 M for A(aq) and 0.650 M for B(aq). There are no other solutes initially. The reaction 2 A(aq) + B(aq) <—> 2 C(aq) + D(aq) takes place. At equilibrium, the concentration of C(aq) is 0.127 M. What is the equilibrium constant of this reaction?

Question 5 :
For the reaction 2 A(aq) <—> B(aq) + C(aq), the standard Gibbs free enthalpy change is 1.64 kJ at 25^oC. The initial concentration of A(aq) is 0.555 M, the initial concentration of B(aq) is 0.301 M, and the initial concentration of C(aq) is 0.243 M. What would be the concentration of A(aq) (in mol/L) once we attain equilibrium (we are still at 25^oC)?

Question 6 :
We start with a pure sample of A(g). The following equilibrium is established:

2 A(g) <—> B(g) + C(g)

The total pressure is 8.40 atm and the temperature is 25.0^oC. The partial pressure of A(g) is 5.06 atm. Calculate the value of the standard Gibbs free enthalphy change (in kJ) for this reaction at 25.0^oC.

.Consider the consumer or patient
perspective in your focus area.
What about family/caregiver
needs? How are they/could they
be engaged in the design or use of
informatics tools and solutions?
How can data, information, and
technology improves
consumer/patient/family
knowledge and decision-making?
There are numerous
contemporary issues that
must be considered related to
consumer health informatics,
for example, trust
considerations with consumer
health data; health literacy;
quality and access issues;
integration of consumer
health informatics and
practice. Briefly discuss how
these issues might be
relevant for your focus area.
How should these challenges
be addressed by practitioners
who may be recommending
web resources or
technologies for patients?
Briefly reflect on these
challenges and issues.
What technology(ies) are in use in
your focus area to support
consumers/patients/caregivers?
What technologies could be
applied to your focus area that are
not currently being used (social
media? Home health devices?
Internet of things?)?
Discuss the legal and/or ethical
considerations for technologies in
your focus area. Are there any
unique regulations or ethical
challenges?
Discuss your vision for the future
of data, information, and
technology in your focus area.
This is your opportunity to think
big what will be the challenges
and opportunities that emerge in
the next 5-10 years?
What are the
social/political/economic factors
that are motivating change and
the role of data and technology in
your focus area?
Revise your concept map to
include concepts from throughout
the course. Include your final
concept map and a brief
description of how it was
developed, what it includes, and
what it does not include in terms
of course topics/concepts.
Final notes: What were your top 3
biggest learning points over the
course of the semester? How will
informatics influence your practice
and/or career goals upon
completion of your DNP program?
Throughout your post, be sure to
demonstrate your understanding
and synthesis of readings and
activities from Weeks
1-8 of the
course (cite course readings,
integrate explanations of
concepts/theories into your
description of informatics in your
focus area). You should expand
on the topics in the prompts
where appropriate to include other
concepts (e.g., mobile health,
patient health records, data
security) from Weeks 7-8,
particularly.
Include at least one additional
informatics
-focused reference
outside of those required for class
readings in your post. Perhaps a
consumer
-focused blog related to
health or your focus area might be
a nice addition.
You should also consider including
any multimedia (images, figures,
videos) that help to describe
informatics in your focus area.
