Explanation / Answer
a. what is the definition of a spontaneous process
spontaneous process = The reaction which is ready to takes place with release of free energy is called as spontaneous process.
b. give a chemical example of a spontaneous reaction, non-spontaneous reaction
spontaneous reaction = C(s) + O2(g) ---> CO2(g)
non-spontaneous reaction = N2(g) + O2(g) -----> 2NO(g)
c. thermodynamics is about the direction, extent, and spontaneity of a chemical reaction.
(i) is there a connection between spontaneity of a chemical reaction and its speed = No, there is no any connection between spontaneity of a chemical reaction and its speed.
(ii) what branch of Chemistry addresses the speed of chemical reactions = Thermodynamics (Second law of thermodynamics)
d. give a chemical example of each of the following types of processes:
(i) reversible = Ice (s) <-----> water(l)
(ii) irreversible = C(s) + O2(g) ---> CO2(g)
