This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.

Video Topics

Entropy (S) is a measure of disorder. The units on S are usually kJ/mol K or J/mol K.

S a change in entropy.

If S is positive, the system is becoming more disordered.

If S is negative, the system is coming less disordered (more ordered)

Disorder can be driving force as seen when 2 gasses mix. H = 0 but the reaction still occurs so there is some energy loss

This video contains multiple examples of processes with a positive S and processes with a negative S. The video also discusses to make this determination.
