Answer: The given reaction is non-spontaneous at low temperatures and spontaneous at high temperatures.
Explanation:
We know that relation between free energy and enthalpy is as follows.
As in the given drawing, solid is converting into gas. This means that there is occurring an increase in entropy of the system. This also means that the enthalpy change will also be positive.
Free energy change is negative (spontaneous) at high temperature and free energy change is positive at low temperature.
Hence, we can conclude that the given reaction is non-spontaneous at low temperatures and spontaneous at high temperatures.
Chemical reaction is given as :
Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.
Mass of hydrogen = 28.0 g (given)
Mass of oxygen = 224.0 g (given)
Number of moles =
Thus, number of moles of hydrogen =
= 14 moles of hydrogen
Number of moles of oxygen=
= 7 moles of oxygen
Now, to find the amount of water:
= 252 g of water.
Thus, amount of water is 252 g (involved in the process).
