What is the name of the thermodynamic barrier that must be overcome before products are formed in a spontaneous reaction?

1 answer:

3 0

Activation energy is a thermodynamic barrier that must be overcome before products are formed in a reaction. It is the minimum amount of energy needed for a reaction to occur. The energy can be in the form of kinetic or potential energy. This concept was introduced by Svante Arrhenius, which brought about the Arrhenius equation which is a formula used to determine rate of reactions.

Given the heat change per mole for the combustion of methanol (-726 kJ/mol), predict the heat change that would occur if 0.200 m

DochEvi [55]

Answer:

-145.2kJ

Explanation:

Enthalpy is an extensive property as its value depends on the amount of substance present in the system.

If the enthalpy for one mole of methanol = -726 kJ/mol;

The Enthalpy for 0.2 mol is given as;

Enthalpy = 0.200 * 726

Enthalpy = -145.2kJ

It would take -145.2kJ for 0.200 mol of methanol to undego the combustion reaction.

Give the name of the reaction that achieves the theoretical limits with respect to free energy in thermodynamics.a. reversible r

Assoli18 [71]

Answer:

The correct option is: a. reversible reaction

Explanation:

In thermodynamics, Gibb's free energy is the quantitative measure of the spontaneity or feasibility of a chemical reaction, at fixed temperature and pressure.

It can also be described as the maximum available work obtained from a closed system. This maximum work can only be achieved in a reversible process, at fixed pressure and temperature.

The Gibb's free energy (ΔG) is given by: ΔG = ΔH - T.ΔS
