Answer 1

Answer:
`\Delta S`< 0

Step-by-step explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

For the reaction
`CaO(s)+CO_2(g)\rightarrow CaCO_3(s)`

In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus
`\Delta S` is negative or less than zero.
