Concept explainers
Interpretation:
Whether the given reaction in problem 3(b) is spontaneous or not at 25° C and 1atm needs to be determined.
Concept introduction:
A spontaneous reaction can be explained as the type of reaction which proceeds automatically to give the product under available conditions.
The best parameter to obtain the spontaneous nature of a reaction is obtaining its Gibb’s free energy change as
The Gibb’s free energy change is obtained by following formula:
Further the change in enthalpy and entropy for reactions are obtained as

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
