Answer:
Option B is correct.
Explanation:
With thermodynamics, one cannot determine the speed of the reaction.
Speed of the reaction is defined as the rate at which one component is changes to another component. With factor cannot be calculated from the thermodynamics branch of engineering.
With thermodynamics we can determine the value of the equilibrium constant,
the extent of a reaction, the temperature at which a reaction will be spontaneous & the direction of a spontaneous reaction. But we cannot determine the speed of a reaction.
Therefore option B is correct.
Answer:
With increased technological knowledge and consequent decreased factors of ignorance, the structures have less inert masses and therefore less need for such decoration. This is the reason why the modern buildings are plainer and depend upon precision of outline and perfection of finish for their architectural effect.
