enthalpy and entropy

Question 1

entropy

Answer 1

measure of disorder/ dispersal of energy in a system
increases the more disordered a system is

Question 2

factors affecting entropy

Answer 2

increases as temperature increases
- particles gain energy and move faster and further apart (more disordered)
- gases have greatest entropy

Question 3

calculating entropy

Answer 3

find the difference between the standard entropies of the products and the reactants

Question 4

gibbs free energy

Answer 4

indicates reaction feasibility
ΔG = ΔH - TΔS
H= change in enthalpy
T= temp in K
S=change in entropy
