Interpretation:
Water evaporation processes from a puddle is considered as spontaneous or not, the reason should be explained.
Concept introduction:
Any natural process or a
In
(b)
Interpretation:
A lion chases an antelope this process is spontaneous or not, the reason should be explained.
Concept introduction:
Any natural process or a chemical reaction taking place in a laboratory can be classified into two categories, spontaneous or nonspontaneous. Spontaneous process occurs by itself, without the influence of external energy. In spontaneous process the free energy of the system decreases and entropy of the system increases. Nonspontaneous process requires an external influence for initiation. In nonspontaneous process the free energy of the system increases but entropy in the system decreases.
In thermodynamics a process is spontaneous if it is taking place by itself without the help of external energy. All spontaneous process will have highly energetic initial state than the final state. This indicates that while the process occurs, there is a decrease in free energy of the system. The increase in randomness also favors the spontaneity of a process.
(c)
Interpretation:
An isotope undergoes radioactive disintegration, this process is spontaneous or non- spontaneous, the reason should be explained.
