Guys The Answer To The Question.
(C). To move oxygen from the air into the body and carbon dioxide from the body into the air.
For question 1:
<span>25°C = 298 K
</span><span>ΔG = ΔH - T ΔS
</span>ΔH= ΔG + TΔS = −91368 + (298)(−284)=−91368-84632=-175730
<span>Therefore ΔH is approx - 176,000 J
</span>
For question 2:
The statement "A negative change in free energy, or −ΔG, represents a spontaneous reaction." is false
