Answer 2

Answer:

Concept:

Spontaneous and non spontaneous process

Explanation:

A spontaneous process occurs without the intervention of a third party. Once initiated, a spontaneous process runs on its own, without the need for constant external assistance. The change in Gibbs free energy for spontaneous processes is negative (G0).

Non-spontaneous processes do not occur on their own. It necessitates constant external influence.

When the continuous external force is removed, a non-spontaneous process will come to a halt.

The change in Gibbs free energy for non-spontaneous processes is positive (G>0).

1) B. A fruit turns yellow as it ripens.

2)D. A cellphone battery is being recharged

Entropy represents the randomness of the particle. As the randomness increases entropy also increases.

3)D. Fast-moving vehicles halt and line up during red light
