One specific substance necessary for muscle activity that is delivered to muscles more efficiently as a result of increased heart rate is blood volume. With increased blood volume, the amount of hemoglobin will increase and this will result in an increased intake of oxygen. This will make a person exercise for a longer span of time.

Under what conditions could some exothermic (ΔH&lt;0) reactions be nonspontaneous (ΔG&gt;0)?
vladimir1956 [14]

Answer:

c. The overall reaction reduces entropy (products have less entropy than reactants).

Explanation:

The free energy change (delta G) for a reaction must have a negative value to allow the reaction to occur spontaneously. Free energy change depends on entropy (S) and enthalpy (H) of the reaction.

ΔG = ΔH  - T ΔS. If a reaction has positive enthalpy change and an overall increase in entropy, the reaction has negative free energy change and occurs spontaneously. However, if a reaction with positive enthalpy change has an overall reduction in entropy, the reaction will have a positive value of free energy change and cannot occur spontaneously.
