Answer #1

Since no physical data is given so its value could be pridicted in term of postive and negtive

1) ∆s would be positive because 3 mole gas and 1 mole solid is giving 2 mole of solid amd 3 mole of gas.

2) ∆s is negtive because no of moles decreases in product hence less randomness

3)∆s is negtive because reactants have 6 mole of has while product has 3 mole of gas

4) ∆s ~ 0 means it aprrosches to zero butits value is less than 0 because size of aluminum atom is more than Fe

5) ∆s is postive because product have more moles of gas.
