A reaction is non-spontaneous at any temperature when
slavikrds [6]

Answer:

A reaction is non-spontaneous at any temperature when the Gibbs free energy > 0.

Explanation:

There is a state function, that determines if a reaction is sponaneous or non spontaneous:

ΔG = Gibbs free energy

A reaction is non spontaneous when it does require energy to produce that reaction. It will be spontaneous, when the reaction does not require energy to be occured.

The formula is: ΔG = ΔH - T.ΔS

ΔH → Enthalpy → Energy gained or realeased as heat.

ΔH < 0 → <em>Exothermic reaction. Spontaneity is favored </em>

T  → Temperature

ΔS → Entropy →  Degree of disorder of a system.

When the system has a considered disorder ΔS > 0, disorder increases.

When the system is more ordered, ΔS < 0, disorder decreases.

The reaction will be non spontaneous if, the enthalpy is positive (endothermic reaction) and the ΔS < 0 (disorder decreases). It will not occur if we do not give energy.

ΔG < 0 → Spontaneous reaction

ΔG > 0 → Non spontaneous reaction

ΔG = 0 → System in equilibrium

What multiplicities are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde?
Flauer [41]

The multiplicities that are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde is a singlet, a triplet, and a quartet. The correct option is E.

<h3>What is off-resonance decoupling?</h3>

Off-resonance decoupling is a process of removing all hydrogen and carbon coupling from a signal except for the place which is near the nucleus or joined with the nucleus.

In NMR also, the coupling of hydrogen and carbon is removed except for the place near the nucleus.

Thus, the correct option is E) a singlet, a triplet, and a quartet.
