A
ΔG
2
Q
Free-energy change
A
A measure that is used to predict whether a reaction is feasible
3
Q
Feasible reaction
A
One that, once started, will carry on to completion without any energy being supplied to it.
4
Q
Free energy change equation
A
ΔG= ΔH -TΔS
5
Q
-ΔH and +ΔS
A
feasible at any temp.
6
Q
Feasible reaction in relation to ΔG
A
ΔG = 0 or less
7
Q
Equation of a straight line
A
y = mx + c
8
Q
Free-energy graph
ΔG,ΔH,ΔS and T
