Answer: A) The reaction is spontaneous above 276 K.
Explanation:
According to Gibb's equation:
= Gibbs free energy
= enthalpy change = +29.3 kJ/mol =29300 J/mol
= entropy change = +106 J/molK
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
for reaction to be spontaneous
Thus the Reaction is spontaneous when temperature is above 276 K.
The empirical formula of this compound is
<u>Given the following data:</u>
<u>Scientific data:</u>
To determine the empirical formula of this compound:
Note: We would assume that the mass of the compound is 100 grams.
Hence, the mass of its constituent elements are:
Next, we would determine the number of moles of each element by using this formula:
<u>For </u><u>hydrogen</u><u> (</u><u>H</u><u>):</u>
Number of moles = 2.0 moles
<u>For </u><u>sulfur</u><u> (</u><u>S</u><u>):</u>
Number of moles = 1.0 moles
<u>For </u><u>oxygen</u><u> (</u><u>O</u><u>):</u>
Number of moles = 4.0 moles
Empirical formula =
