System

Answer 2

The part of a reaction under investigation (what is reacting)

Question 3

Surroundings

Answer 3

Everything but the system

Question 4

Spontaneous changes

Question 5

Standard Conditions for entropy

Answer 5

1 atm, 298 K, normal physical states of substances involved

Question 6

Feasibility

Answer 6

Whether a reaction can occur spontaneously

Question 7
