When a reaction mixture reaches chemical equilibrium, ____.

1 answer:

6 0

When a reaction mixture reaches chemical equilibrium, The forward, as well as reverse reactions, happen at the same rates.

The concentrations of reactants, as well as products, remain unchanged when chemical equilibrium would be reached. It's crucial to keep in mind that both forward but also reverse reactions continue to happen, but at an equal rate.

The system enters a state of dynamic equilibrium when both forward as well as reverse reactions happen at the same rate. Chemical equilibrium happens when all of the reaction's steps reach dynamic equilibrium, or when there gets the balance between the reagents as well as the products is reached.

Therefore, when a reaction mixture reaches chemical equilibrium, The forward, as well as reverse reactions, happen at the same rates.

For a chemical reaction to be spontaneous at all temperatures, which of the following conditions must be met? a. ΔS° > 0, ΔH°

ladessa [460]

Answer:

b. ΔS° > 0, ΔH° < 0

Explanation:

According the equation of Gibb's free energy -

∆°G = ∆°H -T∆°S

∆°G = is the change in gibb's free energy

∆°H = is the change in enthalpy

T = temperature

∆°S = is the change in entropy .

And , the sign of the Δ°G , determines whether the reaction is Spontaneous or non - Spontaneous or at equilibrium ,

i.e. ,

Δ°G < 0 , the reaction is Spontaneous

Δ°G > 0 , the reaction is non - Spontaneous

Δ°G = 0 , the reaction is at equilibrium

The reaction has the value for ∆°H < 0 i.e. negative, and ∆°S > 0 i.e. , positive

Now ,

∆°G = ∆°H -T∆°S

= ( - ∆°H ) - T( + ∆°S )

= ( - ∆°H ) - T( ∆°S )

∆°G = negative

Hence ,

Δ°G < 0 , the reaction is Spontaneous .

1.)What is a chemical reaction?

harina [27]

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Photosynthesis is an example from daily life
