Answer 1

entropy of gas > entropy of aqueous > entropy of liquid > entropy of solid

Reaction 1:

There are more gases in reactant than in product.

So, there is more entropy on reactant side than on product side.

So, entropy change is negative

Answer: negative

Reaction 2:

There are more gases in reactant than in product.

So, there is more entropy on reactant side than on product side.

So, entropy change is negative

Answer: negative

Reaction 3:

There are more gases in product than in reactant.

So, there is more entropy on product side than on reactant side.

So, entropy change is positive

Answer: positive

Reaction 4:

Entropy of aqueous is more than solid.

So, there is more entropy on product side than on reactant side.

So, entropy change is positive

Answer: positive

Reaction 5:

There are gases only on reactant side.

So, there is more entropy on reactant side than on product side.

So, entropy change is negative

Answer: negative

Reaction 6:

There are gases only on reactant side.

So, there is more entropy on reactant side than on product side.

So, entropy change is negative

Answer: negative

Answer: reaction 3 , reaction 4
