Which statement about spontaneous and non spontaneous processes is correct?

option A is correct option.

Explanation :

A spontaneous method is capable of continuing during a given direction while not having to be driven by an outdoor supply of energy.

The laws of physical science govern the direction of a spontaneous method, guaranteeing that if a sufficiently sizable amount of individual interactions are concerned, then the direction can perpetually be within the direction of enhanced entropy.

Associate in Nursing endergonic reaction (also referred to as a nonspontaneous reaction) may be a chemical change during which the quality change in free energy is positive and energy is absorbed.

Endergonic processes will be pushed or force by coupling them to extremely exergonic reactions.

ΔG = ΔH - TΔS , ΔG is amendment within the free energy, ΔH is that the amendment in total heat, ΔS is that the amendment in entropy and T is temperature in kelvin.

Spontaneity of reaction Vs total heat Vs entropy

When ΔH is negative and ΔS is positive, ΔG are going to be negative over all temperatures.

When ΔH is negative and ΔS is negative, ΔG are going to be negative at low temperatures.

When ΔH is positive and ΔS is negative, ΔG won't be negative at any temperature. There would be no spontaneous reaction.

When ΔH is positive and ΔS is positive, ΔG are going to be negative at high temperatures.

Therefore, finally it's the amendment in free energy of a reaction which may predict if a reaction is possible.

b is the correct answer

mark me brainliest and hope this
