Answer:
The temperature above which the reaction be spontaneous is 331.3 K.
Below this temperature; the backward reaction is the favored reaction.
Explanation:
- We have an important relation from the third law of thermodynamics:
<em>ΔG = ΔH - TΔS</em>
<em>ΔG is the free energy change of the reaction,</em>
<em> ΔH is the enthalpy change of the reaction,</em>
<em>ΔS is the entorpy change of the reaction,</em>
- <em>The reaction is spontaneous when ΔG is negative.</em>
- and ΔG be negative when the value of (TΔS) is higher than the value of (ΔH).
<em>When ΔG = 0, ΔH = TΔS.</em>
For this reaction, ΔH = 30.91 KJ and ΔS = 0.0933 KJ/K.
- The temperature above which the reaction be spontaneous is:
T = ΔH / ΔS = (30.91 KJ) / (0.0933 KJ/K) = 331.29 K ≅ 331.3 K.
<em>∴ The temperature above which the reaction be spontaneous is 331.3 K.</em>
<em>Below this temperature; the backward reaction is the favored reaction.</em>
The order is
1CH4 + 2O2 ----------- 1CO2 + 2H2O

Answer:
<h3> GLACIERS AND ICE CAPS </h3>
Explanation:
According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
