free energy change Flashcards
1
Q
what is free energy change used to measure
A
used to predict whether a reaction is feasible or not
2
Q
in order for a reaction to be feasible what should ΔG be
A
if ΔG is negative or zero then the reaction may take place itself
3
Q
what is the formula for free energy change
A
ΔG = ΔH - TΔS
where ΔH is enthalpy change and T is temperature ( in K ) and ΔS is entropy change
