1) Thermodynamics is not concerned about.........
(i) energy changes involved in a chemical reaction.
(ii) the extent to which a chemical reaction proceeds.
(iii) the rate at which a reaction proceeds.
(iv) the feasibility of chemical reaction.
The answer is option (iii) the rate at which a reaction proceeds.
Explanation: Thermodynamics is actually concerned with the initial and final states of a system and not with the rate at which the transformations take place. The laws can be applied to a system only when the system is in equilibrium.
