Answer:-
2747.7 Cal mol -1
Explanation:-
Molar heat of Fusion is defined as the amount of heat necessary to melt (or freeze) 1 mole of a substance at its melting point.
Atomic mass of Iron = 55.845 g mol-1
Mass of Iron = 200 g
Number of moles of Iron = 200 g / (55.845 g mol-)
= 3.581 moles
Heat released = 9840 Cal
Molar heat of Fusion = Heat released / Number of moles
= 9840 Cal / 3.581 moles
= 2747.7 Cal mol -1
Answer:
Explanation:
A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
h2 + 02 = h2o

1 cup = 2 pints
48 × 2 = 96 pints

Free energy is used to determine how systems change and how much work they can produce.
If the free energy of the reactants is greater than that of the products, the entropy will increase when the reaction takes place so the reaction will tend to take place spontaneously. If the free energy of the products exceeds that of the reactants, then the reaction will not take place
The Gibb's free energy change (ΔG) is:
ΔG<0⟶ Spontaneous process
ΔG>0⟶ Non-spontaneous process
ΔG=0⟶ Equilibrium process or reversible process
Gibb's free energy is a quantity used to measure the maximum amount of work done in a thermodynamic system , when the temperature and pressure are constant .
It is a state function hence it doesn't depend on path .
ΔG = ΔH - T(ΔS)
