Predict in which of the following reactions, entropy increases/decreases
`2NaHCO_(3) rarr Na_(2)CO_(3)(s) + CO_(2)(g) + H_(2)O(g)`

Text Solution

Verified by Experts

Reactant is a solid and hence has low entropy. Among the products there are two gases and one solid. So the products represent a condition of higher entropy.
