Answer:
For the reaction to be spontaneous at high temperatures, ΔG < 0 and, ΔH > 0 and ΔS > 0.
Explanation:
According to the Gibbs free energy equation, for the reaction to be spontaneous at high temperatures when it was not spontaneous at low temperatures, the free energy change ΔG < 0.
Since ΔG = ΔH - TΔS where ΔH = enthalpy change and ΔS = entropy change,
For ΔG < 0 at high temperatures, ΔH > 0 and ΔS > 0. That is both ΔH and ΔS are positive at high temperatures.
<u>So, for the reaction to be spontaneous at high temperatures, ΔG < 0, and ΔH > 0 and ΔS > 0.</u>
The statement is true. The relationship between the kinetic energy of molecules and the temperature of these molecules are in direct proportionality. Therefore, the temperature generally increases as average kinetic energy also increases. We can relate the two qualities using the Boltzmann equation.
Answer:
Total volume is 625 mL
Explanation:
We use the 6 % (m/v) data which is a sort of concentration. This percent means that the solution has 6 g of solute in 100 mL of solution
So we make a rule of three:
6 g of solute (NaCl) are in 100 mL of solution
Therefore, 37.5 g are in (37.5 .100) / 6 = 625 mL
Sulfur atom= number of moles of the compound * number of sulfur atoms * Avogadro’s numbers
So it’s
4.6*1*6.022*10^23
