Concept explainers
(a)
Interpretation: The validation of the given statement, “Increasing temperature increases reaction rate” is to be stated.
Concept introduction: According to Le Chatelier’s principle, equilibrium of the reaction shift towards the side that involves absorption of heat when the temperature is increased. The kinetic energy of molecules increases on increasing the temperature. It results in the faster rate of the reaction.
(b)
Interpretation: The validation of the given statement, “If a reaction is fast, it has a large rate constant” is to be stated.
Concept introduction: The rate constant is represented by
(c)
Interpretation: The validation of the given statement, “A fast reaction has a large negative
Concept introduction: The change in Gibbs free energy, enthalpy and entropy is represented by
The change in Gibbs free energy describes the spontaneity of the reaction. The change in enthalpy describes the relative bond strength in the substance, whereas the change in entropy describes the randomness in the system.
(d)
Interpretation: The validation of the given statement, “When
Concept introduction: The activation energy
(e)
Interpretation: The validation of the given statement, “Fast reactions have equilibrium constants
Concept introduction: The change in Gibbs free energy is represented by
If the
(f)
Interpretation: The validation of the given statement, “Increasing the concentration of a reactant always increases the rate of a reaction” is to be stated.
Concept introduction: The concentration of a reaction influences the rate of a reaction. The increase in concentration of a starting material results in increase of the rate of a reaction.
