Gibbs free energy

Question 1

What is the Gibbs free energy equation?

Answer 1

/\G = /\H - T(/\S /1000)

Question 2

How do you show whether a reaction is feasible depending on its exothermic/endothermic and its order? (outline answer)

Answer 2

/\H is positive/negative (endothermic/exothermic)
/\S is positive/negative (more disordered/ordered)
so -T/\S is negative/positive
therefore /\G is always negative/positive
(if negative its feasible)
(if it’s possible (-/\H +T/\S) (+/\H -T/\S) explain temperature needed)
